You have two attempts at your subject test for each subject. If you pass the test at your first attempt, you’ll instantly be able to tutor in that subject. Unfortunately, if you fail both attempts of a test, you will not be eligible to tutor in a subject. The passing scores for the subject tests vary by subject but are generally around 7/10 or 8/10. Unfortunately you won’t be able to re-take the test after two failed attempts.
