Too Late? Watch

Doing Chemistry + Maths A level and i’ve practically completed the Chemistry content.

I have about 4/5months to my exams and i’ve hardly begun the maths content.

My question is, since I only have 1 subject to worry about as of now, is 4/5 months enough time to achieve minimum B for maths? self taught? (teachers are trash)

If so, how should it be done, any tips? i’m not the most gifted mathematician unfortunately.
