I finish 3/4 of the math for this year in the holidays and now I have no motivation to do anything. Everything we do in class is dry and i can't find the excitement for maths I had in the holidays. My grades are falling cause of this since I can't be bothered revising. What do I do?

about me:
Im in year 12 we did basic complex numbers, vector calc, diff, diff eq, integral and kinematics
