Question 20 of 20

Practice Tests are important.

Take another test.
Continue learning.

Taking practice tests is very important because they indicate what your knowledge gaps are.

It’s important that you know what your weak points are so you can focus on learning these topics.

Recent GED graduates have some good advice for you: don’t try to learn for all four GED tests at once.

You are allowed to take one of the four GED tests at a time, so prepare for one subject area, take that test, and move on to next subject field.

When preparing for the GED test, the most common mistake is to forget to block your time for learning.
