Should I buy ready-made TMAs?

Guys, I am a student from NIOS secondary, and I'm very paranoid, I am scared that my answers for TMA might be wrong, so there's a youtube channel called Manish Verma Official, they provide some TMA services, as in like by paying 500 RS to them, they will get professionals to create TMAs for you and also upload,
So I was wondering, should I go for it? or if not, are there any other sources I can use to ensure 100% accuracy for my TMAs?
