High school brings with it an enormous set of challenges that can make any student feel overwhelmed. You aren’t just asked to succeed in your classes, but also in sports, and extracurricular activities, all while still making time for family and friends. Even the best students can find demanding high school classes an enormous struggle, especially as they prepare to put together college applications and for success on challenging standardized exams. Whether you need Chemistry tutoring in Philadelphia, Chemistry tutoring in Milwaukee, or Chemistry tutoring in Portland, working one-on-one with an expert may be just the boost your studies need.

High school chemistry is one of the toughest courses you can face over your high school career. When thinking of such a course, you probably have thoughts of Bunsen burners and mysterious reactions in cloudy beakers, but you will also be challenged to complete complicated mathematics problems and visualize complex molecular shapes. Perhaps the most challenge of the course, you will be asked to link what you learn in chemistry to other classes as diverse as algebra and biology. These more mundane tasks in chemistry are often the most important, and what give students the greatest challenges. Varsity Tutors offers resources like free High School Chemistry Practice Tests to help with your self-paced study, or you may want to consider a Chemistry tutor.

Chemistry especially rewards students who make time to visualize the complex molecular world and appreciate its scale. Understanding the conceptual foundations of chemical reactions instead of just going through the passive motions offers far better prospects for success now and into the future. Consider, for instance, that there are more molecules in ten drops of water than there are stars in the entire universe! Let that thought sink in for a moment, and you can begin to appreciate the amazing world of matter and reactions that you will study in chemistry. Keeping this sense of scale and maintaining an appreciation of the context in which chemical processes function are each enormously important.

In short, if something can happen in a reaction system, it generally does. Because of the enormous numbers involved, chemistry is therefore a study of the overall behavior of matter, and much less the study of individual atoms. Maintaining this perspective is important to success in high school chemistry, because visualizing the proper scale on which reactions occur is essential. Only with the proper scale do things like thermochemistry and reaction kinetics make sense. In addition to the High School Chemistry Flashcards and Chemistry tutoring, you may also want to consider taking some of our High School Chemistry Diagnostic Tests.

This ability to visualize and contextualize abstract concepts will not just serve you well in chemistry, but can serve you well in a wide variety of courses. Consider the advantage you will have if you can visualize the functioning of a cell in biology, or the forces of a magnet in physics. Understanding concepts offers extensive advantages over more passive methods like rote memorization.

Developing these skills is not easy. They take time, deliberate effort, and may not be stressed in your class textbooks or by your teachers. You may want to work collaboratively with other students in groups to make visualization easier. Additionally, you may find that it is necessary to actively seek out new and innovative materials for your class. Online videos, practice questions, and private tutors are all things worth considering. Varsity Tutors’ Learning Tools question database provides free high school chemistry flashcards that you can employ as one such additional resource. Our flashcards are organized by content in a way that allows you to review general or specific concepts, and each card includes an explanation of how the correct answer was calculated or determined. You can use our high school chemistry flashcards online or, when you are away from a computer, through Varsity Tutors’ free app. Our high school chemistry flashcards can be a useful tool as you learn and review the many concepts on which one’s success in a high school chemistry course depends. You will have to take charge of your own chemistry education to maximize its impact. However, the time you invest now can help you add critical skills to your intellectual toolbox that you can continue to use years into the future.

Take the Varsity Learning Tools free diagnostic test for High School Chemistry to determine which academic concepts you understand and which ones require your ongoing attention. Each High School Chemistry problem is tagged down to the core, underlying concept that is being tested. The High School Chemistry diagnostic test results highlight how you performed on each area of the test. You can then utilize the results to create a personalized study plan that is based on your particular area of need.

High School Chemistry is often the first time students are introduced to concepts in the physical sciences. Unlike biology, Earth and space sciences, and environmental sciences, chemistry is governed by strict mathematical constructs and principles. High School Chemistry allows students an opportunity to apply mathematical and reasoning skills outside of math classes, developing an understanding for chemical systems and reactions on a molecular level. Whether you need top Chemistry tutors in Syracuse, Chemistry tutors in Chicago, or top Chemistry tutors in San Francisco, working with a pro may take your studies to the next level.

Most High School Chemistry classes begin with an introduction to elements and compounds, with a focus on atoms and molecules, respectively. Students gain familiarity with elemental properties, groupings, and the periodic table. Solution chemistry is also introduced early in the course, focusing on solubility rules and precipitate formation. Electron configuration is used to introduce Lewis dot structures and bonding principles, with a focus on the differences between ionic and covalent bond formation and the development of intermolecular forces. Students will then become familiar with VSEPR geometries, orbitals, and hybridization. These topics will all be covered before reaction chemistry, which will build a strong fundamental foundation. Varsity Tutors offers resources like free High School Chemistry Diagnostic Tests to help with your self-paced study, or you may want to consider a Chemistry tutor.

Introductions to reaction chemistry will focus on the four principle reaction types: addition (synthesis) reactions, dissociation (decomposition) reactions, single-replacement reactions, and double-replacement reactions. Some courses will classify specific reactions (such as oxidation-reduction, acid-base, or combustion) as their own categories. Balancing chemical equations and understanding stoichiometry become essential components to the course. Students will frequently be asked to make several stoichiometric conversions to arrive at an answer. Manipulating given quantities is an essential skill in High School Chemistry, and will be tested through questions about limiting reagents, precipitate formation, and other conversion questions. In addition to the High School Chemistry Practice Tests and Chemistry tutoring, you may also want to consider taking some of our High School Chemistry Flashcards.

High School Chemistry has a heavy foundation in math, and may require formula memorization. Most formulas will revolve around the properties of gases, chemical equilibrium, and pH, though different courses may introduce different formulas. It will be important to know the gas laws and relationships regarding the equilibrium constant of a reaction; pH and acidity are commonly tested in High School Chemistry, and you will need to be familiar with exponents and logarithms in order to solve these types of questions.

Some High School Chemistry courses will include a laboratory component, which will emphasize the scientific method, hypothesis formation, and chemical procedures. Students should be prepared to analyze solution chemistry, acids and bases, and stoichiometric principles in a hands-on environment. Titrations often play a large role in the laboratory portion of High School Chemistry.

After taking a course in High School Chemistry, students will have a solid understanding of several relationships between observable phenomena and the mathematics governing those phenomena. This will serve as a tool for understanding physical chemistry and relationships in any physics or chemistry endeavors that students face in the future.

20 Practice Chemistry Tests

Unit Conversion

Converting from one unit of measurement to another is a basic scientific skill. This test covers unit conversions between metric units and English units. Rember to use unit cancellation to easily figure units in any science problem.

Temperature Conversion

Temperature conversions are common calculations in chemistry. This is a collection of questions dealing with conversions between temperature units. This ​is important practice because temperature conversions are common calculations in chemistry.

Reading a Meniscus in Measurement

An important laboratory technique in a chemistry lab is the ability to accurately measure a liquid in a graduated cylinder. This is a collection of questions dealing with reading the meniscus of a liquid. Remember that the meniscus is the curve seen at the top of a liquid in response to its container.

Density

When you're asked to calculate density, ensure that your final answer is given in units of mass—grams, ounces, pounds, or kilograms—per volume, such as cubic centimeters, liters, gallons, or milliliters. The other potentially tricky part is that you may be asked to give an answer in units that are different than those you are given. Review the unit conversion test questions above if you need to brush up on unit conversions.

Naming Ionic Compounds

Naming ionic compounds is an important skill in chemistry. This is a collection of questions dealing with naming ionic compounds and predicting the chemical formula from the compound name. Remember that an ionic compound is a compound formed by ions bonding together through electrostatic forces.

The Mole

The mole is a standard SI unit used primarily by chemistry. This is a collection of test questions dealing with the mole. A ​periodic table will be useful in helping complete these.

Molar Mass

The molar mass of a substance is the mass of one mole of the substance. These test questions deal with calculating and using molar masses. An example of a molar mass might be: GMM O2 = 32.0 g or KMM O2 = 0.032 kg.

Mass Percent

Determining the mass percent of the elements in a compound is useful to find the empirical formula and molecular formulas of the compound. These questions deal with calculating mass percent and finding empirical and molecular formulas. When answering the questions, remember that the molecular mass of a molecule is the total mass of all the atoms making up the molecule.

Molecular Formula

The molecular formula of a compound is a representation of the number and type of elements present in one molecular unit of the compound. This practice test deals with finding the molecular formula of chemical compounds. Note that the molecular mass or molecular weight is the total mass of a compound.

Theoretical Yield and Limiting Reactant

Stoichiometric ratios of the reactants and products of a reaction can be used to determine the theoretical yield of the reaction. These ratios can also be used to determine which reactant will be the first reactant to be consumed by the reaction. This reactant is known as the limiting reagent. This collection of 10 test questions deals with calculating theoretical yields and determining the limiting reagent of chemical reactions.

Balancing Chemical Equations

You probably won't get far in chemistry before needing to balance a chemical equation. This 10-question quiz tests your ability to balance basic chemical equations. Always start by identifying each element found in the equation.

Balancing Chemical Equations No. 2

Being able to balance chemical equations is important enough to have a second test. After all, a chemical equation is a type of relation you will encounter every day in chemistry.

Concentration and Molarity

Concentration is the amount of a substance in a predefined volume of space. The basic measurement of concentration in chemistry is molarity. These questions deal with the measurement molarity.

Electronic Structure

It is important to understand the arrangement of electrons making up an atom. Electronic structure dictates the size, shape, and valence of atoms. It also can be used to predict how electrons will interact with other atoms to form bonds. This test covers the concepts of electronic structure, electron orbitals, and quantum numbers.

Ideal Gas Law

The ideal gas law can be used to predict the behavior of real gasses in situations other than low temperatures or high pressures. This collection of questions deals with the concepts introduced with the ideal gas laws. The Ideal Gas Law is the relationship described by the equation:

PV = nRT

where P is pressure, V is volume, n is the number of moles of an ideal gas, R is the ideal gas constant and T is the temperature.

Equilibrium Constants

Chemical equilibrium for a reversible chemical reaction occurs when the rate of the forward reaction equals the rate of the reverse reaction. The ratio of the forward rate to the reverse rate is called the equilibrium constant. Test your knowledge about equilibrium constants and their use with this 10-question equilibrium constant practice test.

Solving Chemistry Problems

Topic Review on "Title":

Problem-solving can be a very difficult task.  But when a specific “attack” is used, the problems can be solved much more easily.

General Problem-Solving Technique

A technique for solving any type of problem involves:

  • Identify what’s being given
  • Clarify what’s being asked
  • Select a strategy (trial and error, search, recall, deductive reasoning, working backwards, etc)
  • Solve using the selected strategy
  • Review your answer

Problem-Solving Technique for Word Problems

A problem-solving strategy that turns the above “general” strategy into a strategy specifically for solving word problems is the KUDOS method:

  • K = Known (identify the known)
  • U = Unknown (identify the unknown)
  • D = Definition (identify definitions, equations, equalities, constants needed)
  • = Output (use your definitions to output an answer)

S = Substantiation (check appropriateness, units and significant figures of your answer).

Preparing for a Test

There are several tips to help you prepare for a test:

  • Stay ahead of the game.  Don’t wait until the last minute.  If you wait until the last minute to prepare, there won’t be time to seek out help if you encounter problems.
  • Make a cheat sheet.  Even if you can’t use it on the exam, making a concise “cheat sheet” helps you focus in on key information and is a great study technique.
  • Know the format of the exam and what information is “test-able” (what you’ll be responsible for).  Ask your instructor well in advance for this information.
  • Make a mock-exam.  Select the key information and make a practice exam for yourself.
  • Attend any review sessions offered, even if they are optional.  Often, key information is given in these sessions that is not said in the general class period.
  • Get help early.  If you have any problems, seek out your instructor ahead of time.  Instructors do not like last minute cramming questions. 

Taking a Test

Several tips can help improve your test scores:

  • Arrive early and be prepared.  Rushing can increase anxiety and decrease performance
  • Listen and read instructions carefully.  Your instructor may give changes to the questions or instructions.  Don’t assume you know what a problem is asking…always read the instructions!
  • Memory dump.  On the back or top of the test, write all information you’ve been “storing” in memory.  This allows a “bank” for you to refer to as you work through the test and prevents anxiety about forgetting information.
  • Skim the test and make a plan.  Budget your time accordingly.
  • Answer questions sequentially.  Often information from previous problems is used later in the test—try not to skip around.
  • Apply the guessing rule.  Don’t randomly guess, but if you can eliminate a few of the selections, guess among the remaining.
