I use Seneca for Science and Maths but i honestly feel like its not helping. I complete a section but then forget, the problem is that i lose interest. I got 3s and 4s in my mocks but that was because i barely revised. Revision is the worst for me, i hate procrastinating but i still do it, and i have upcoming mocks again in March and i still feel its so difficult to cover everything. I feel like a failure.
