I wasted my 11th (forreal)

im giving jee in 2026 and as the title says. i have absolutely nothing done thoroughly. basic concepts might be there for some chapters (mostly only maths) but i havent practiced any chapter thoroughly. im not asking for sympathy or validation. im going to start working as hard as i can from now on, because i cant waste my time and energy into thinking if its still possible or not. I'll be frank, a few motivational words might push me even further, so feel free to do so but my main point of the post was to ask for tips. please share as many tips as you can, baaki ka mai try karti hu. drop lena plan mei nahi hai. iit ki ummeed bhi zyada nahi, but i do hope to achieve a tier one college like bits. to be fair, bitsat also happens in may so i feel like comparatively zyada time bhi hai. wish me luck!
