How much time needed to cover backlog and Cutoff in 2026

i am a JEE aspirant i want to crack JEE Advance to study in IITM i belong to OBC cat egory and i am a male dude to health reasons i couldnt attend coaching classes first 3 months of 11th how should i prepare myself to cover my backlog and how much will be predicted cutoff for 2026 for B.Tech in EEE

By my personal experience of not paying attention to classes for first few months as I have always been a last resort preparer,It’s best to create few tasks or targets to clear in your free time like when you get off classes or the breaks you get
The only companion in these cases is your own organisation skills
Your backlogs can be completed faster if you have someone else with the similar problem so you can discuss and complete faster but it takes a bit extra hardwork to complete your backlogs and to keep up the competition with your friends
As for the cutoff it’s best if one refers to josaa cutoffs of prev and upcoming years
as it is subjected to change
