Hi, I'm an highschool student and I had some problem studying. I've always been fast in lerning things so I never really had the need to study, but now the subjects are becoming too much and complex and in general I'd also like too study those things. I'm having an hard time studying and concentrating especially in subject I'm late with, I'm also developing a bit of negative thinking (that destract me even more). I feel like i would just need to learn how to do this, how to get started. What would you do? Do you got any advice too get started?
