CAEC Science Preparation Course 2026

This course is for adults in Canada who are getting ready for the Science test of the Canadian Adult Education Credential (CAEC). It follows the three official strands: the nature of science, scientific inquiry skills and science, technology, society and environment, with most practice on reading experiments, tables and graphs. Study each lesson, try its topic quiz, then take the timed 35-question final assessment. Score 80% or more to get a certificate of completion.

专题测验1：The Science test and the nature of science

考前须知

The CAEC replaced the GED® in 2024. Completed GED® credentials stay valid.
There are five CAEC tests: Reading, Writing, Mathematics, Science and Social Studies. Your credential is issued when you pass all five and/or meet PLAR requirements.
The Science test has 35 questions in 90 minutes.
The Science test has three strands: nature of science (10–25%), scientific inquiry skills (60–85%), and science, technology, society and environment (5–15%).
Most Science questions (50–80%) are of moderate complexity: applying concepts, choosing an approach or selecting tools, rather than simple recall.
You need 55% to pass. 80–100% is "exceeds minimum standard" and 55–79% is "meets minimum standard".
Calculators may be used only on Part II of the Mathematics test. Dictionaries, thesauruses and translators are not permitted on the Science test.
You may write a subject test once per calendar month and up to 3 times per calendar year. A sample test is available in each subject on the CAEC digital platform.

常见问题

Is this the official CAEC Science test?

No. This is an independent practice course. It is not run by the CAEC Testing Service or any province or territory, and your scores here are not CAEC results.

What does the certificate from this course show?

The certificate of completion shows that you finished this practice course and scored at least 80% on its final assessment. It is not the CAEC, not a high school equivalency and not an official result, so schools and employers will not accept it in place of the CAEC.

Do I need to memorize a lot of science facts?

Less than you might think. Most of the test (60–85%) is scientific inquiry skills, such as finding variables, reading tables and graphs and judging conclusions. Practise those skills with the scenarios in this course.

Can I use a calculator on the Science test?

The CAEC Test Administration Guide allows calculators only on Part II of the Mathematics test. Practise simple arithmetic, such as averages, differences and unit conversions, by hand.

Why is the pass mark 80% here when the CAEC needs 55%?

The real test needs 55%. We set a higher bar so that a pass here is a good sign you are ready, not just close.

Where do I register for the CAEC?

Eligibility rules, fees and testing centres depend on your province or territory, so start with your provincial or territorial CAEC page. You then create an account on the CAEC digital platform and book a test at a testing centre.
