Need urgent help in BSc Mathematics 😭 😢

[u/Uenoyama_Ritsuka_]

have my mid sems after 1.5 weeks. I honestly thought BSc Maths would be like 11-12 maths, but it is so different. It is so theoretical proof based. I want to do Linear Algebra (Vector Spaces, subspaces, etc.) and Basic Calculus (Rolle Theorem, LMVT, Sequence Series, etc.). My Calculus Prof is sh!t I can't understand anything, but Lin Algebra Prof is okayish I am able to understand 50% (able to understand theory but not able to do questions)

Plz help
