专题测验1：The GED Math test, the calculator and a plan

考前须知

The GED Math test takes 115 minutes, including 2 minutes of instructions and final review and a 3-minute break between its two parts.
An onscreen calculator is available on Part 2, and you may bring your own TI-30XS to a test center. A calculator reference sheet and a math formula sheet are on screen.
The Mathematical Reasoning test has 46 questions, according to South Carolina's state GED subject flyer.
You need a score of at least 145 on each of the four GED subjects to earn your high school equivalency.
Scores of 165–174 are College Ready and 175–200 are College Ready + Credit, which may earn college credit depending on the program.
About 45% of the test is quantitative problem solving and about 55% is algebraic problem solving.
To test online, you must be in the United States and score “green” on the GED Ready® practice test within the last 60 days. You cannot use a physical calculator or scratch paper online.
This course is for the US GED® test. In Canada, the Canadian Adult Education Credential (CAEC) replaced the GED® in 2024.

常见问题

Is this the official GED Math test?

No. This is an independent practice course. It is not run by GED Testing Service, and your scores here are not GED® 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 a GED® credential, not a high school equivalency and not an official score, so schools and employers will not accept it in place of the GED®.

Why is the pass mark 80% here when the GED needs 145?

The GED uses a score scale where 145 is the passing score on each subject; it is not a percent. We set a high bar of 80% so that a pass here is a good sign you are ready.

Can I use a calculator on the GED Math test?

Only on Part 2. It has an onscreen TI-30XS calculator, and at a test center you may bring your own TI-30XS. On the online test you cannot use a physical calculator. Practice Part 1 skills by hand.

Is the GED for people in Canada?

This course is about the US GED® test. In Canada, the Canadian Adult Education Credential (CAEC) replaced the GED® in 2024, so Canadian adults should prepare for the CAEC instead.

How do I sign up for the GED Math test?

Create an account on ged.com, then choose a test center or online testing, pick your subjects, a date and a time, and pay online. Prices and rules depend on your state.
