Books or web pages may offer students either revision or practice exercises at different stages of the learning process. When you first start studying a subject you need some basic input and after, you may wish to test your newly-acquired knowledge by doing some basic practice exercises. Much later, when you have progressed and read or studied a lot about the subject, you may again like to test yourself (possibly before an exam) with some revision exercises - so as to identify any areas of weakness.
"What are you doing now, Ann?"
"I'm just going through some revision exercises before the exam."
If the subject is Maths then they can be referred to as Maths questions/Maths problems/math exercises.
If it is another subject they can be called (subject) questions/exercises
Revision questions/exercises are a list of questions to help you remember what you have learned and help you practice it.
Revision/Practice questions are usually at the end of each topic so that you can practice more on that topic.
This helps you to be able to understand the topic better.

If the questions are specifically to prepare for a test you would call these exam practice questions or exam revision questions.
