This test is divided up into 4 sections. Once you have finished all of the sections, you will get your math and reading scores.
You cannot “save” a section for later, and once a section’s timer has run out, you cannot go back to work on that section again.
You can take breaks between the sections, and you do not have to complete the whole practice test in one sitting.
The first part is Reading. It is 65 minutes and has 52 questions.
