So i wasted kind of all my time to study in the past few months (not kinda my fault but kinda my fault, our teacher gives us heavy hw and other stuff to at home and they teach like shit, and i am always sleepy during class) and i have 1 month left before half yearly and our half yearly syllabus is 70% of the total syllabus how do i study for it Edit - class 12th and i also have applied maths

I am kinda bored at thought how to build one at home. As the area in which i live in is kinda scary so i might need it once in my life
