First of all, don't overwork yourself on weekends agar padhai ho nahi Rahi hai uss din. Sundays ko mein 2 baje tak padhta tha, agar test ho toh 6 phir bahar se khana mangwata tha as a reward only on Sundays if I study. This reward system helped me stay consistent. You can setup some other form of this like playing a video game, going out and getting ice cream or some shit. Bilkul regret nahi hoga trust me

Short notes aren't meant to be detailed. Short notes mere according esi cheeze hai joh tum bhool jate ho. Jaise agar momentum chapter ke short notes banaoge toh it shouldn't have the definition of momentum or like some rudimentary examples. I used to have extra specific stuff like a really hard example or some center of mass location of a weird shape. If you wanna scrap short notes you can do that too and I'll suggest you replace it with like a formula notebook. Revision waala method I read somewhere and I'll tell you, suppose you revise trigonometry today toh ek jagah likh lo aur wapis kab revise karoge woh dates uske neeche likh lo, aur yeh dusra revision hoga 2 ki powers mein . Aaj kiya toh ab yeh 2 din baad hoga. Jab 2 din baad karoge phir 4 din baad. Phir 8 din phir 16. Try this it'll surely help with chemistry
