Become a tutor Tutor FAQs Do I have to have an A grade at GCSE in the subject I would like to tutor? In the first instance we look to your GCSE grades. We ask that applicants to be Primary tutors have at least an A and B in English and Maths (in either combination). For Secondary tutors we ask that applicants have an A grade in the subject you wish to tutor. If you do not have an A grade in your chosen subject but have an equivalent or higher qualification, we will still consider your application.
