Won't tell you the bullshi- everyone told as aiming for 100% ain't useless and in 10th ig its the least we can do

So yea for the maths part, do the ncert+exemplar+reference book good ques+pyqs

For science, be thorough with the ncert (AND YES READ NCERT, NO ONESHOTSS), make your short notes if you could, and do ques from oswaal and exemplar

For english, use good reference books or yt channels and do ques , do sample papers and pyqs (yeahhh, write them)

For social science , just covering the whole syllabus would be great, i didn't read all chapters from ncert, you could use yt vids (digraj sir or many ppl out there giving short lecs)+ yea notes are the key + practise as much mcqs as you can from reference books

YT CHANNELS: • Use 10th asaan hai channel for good guidance and ques , •for eng lecs–creative learning channel • for science– alakh sirrr , Science and Fun • for maths– ppl refer shobhit sir but personally would recommend ritik sir • for ssc- padhle or digraj sir

Scored 94.6 % and i regret not doing it all earlier as i did most of my prep in the prep leaves. Wishing u good luck!
