I had just taken my Calculus final and found out to much woe that I got 20% on my exam.

I have tried doing problems and memorizing important blurbs in my book and such but everytime I memorize one detail, I seem to forget the one before it.


How much am I really supposed to dedicate to learning calculus? This is the second time that I have failed this class and I have gone to office hours and did additional learning and tutoring.


Any tips while I prepare to take this class again for the third time?


And I have a history of doing very poorly in Math as I've failed Algebra 4 times, Geometry twice, and Algebra 2 twice. But I do well in English and Art.
