What you are given

The real test supplies a periodic table, a chemistry reference sheet and an on-screen scientific calculator, and allows 2 hours 30 minutes. The timed exam here draws 42 of the 50 questions in 90 minutes, the same pace.

Worked, with sources

Many questions are calculations with numbers chosen to be worked by hand, and the explanation shows the working. Each links the public page its rule was read on.

  • Competency 4 is the largest and the most numerical: balancing, mole ratios, limiting reactants, rate laws, pH, buffers and cell potentials.
  • The outline asks for electron configurations and orbital filling diagrams only for elements 1 to 56 and their ions.
  • Competency 8 names guidelines: the American Chemical Society, the EPA, material safety data sheets, the National Science Teachers Association and the Americans with Disabilities Act.

Questions and answers

Is there a free FTCE Chemistry 6-12 (003) study guide?

Yes. The official one is the test information guide on the FTCE site, with the competencies and skills for Chemistry 6–12. This page adds 50 practice questions of our own, each tagged with its competency and a public source.

Is there a free online FTCE Chemistry practice test?

This one is free and runs in the browser with no account: 50 questions with explanations, and a timed exam. None is taken or reworded from a real test or from the guide's sample questions.

How many questions are on the FTCE Chemistry 6-12 test?

Approximately 70 multiple-choice questions, taken on a computer. The FTCE site notes that some questions may be under evaluation for future tests and do not affect a score.

What is a passing score on FTCE Chemistry 6-12?

The FTCE site states it as a scaled score of at least 200. That is not a percent, so the timed exam here reports the number right and gives no pass or fail.

Can you use a calculator on the FTCE Chemistry test?

An on-screen scientific calculator is provided, and examinees may not bring their own. The FTCE site says hand-held calculators and paper reference sheets may be available upon request.
