The honest answer is that doing JEE prep alongside startups is genuinely difficult.

I don't recommend it unless you seriously care about both.

My structure is simple: four 90-minute JEE blocks, six days a week.

Everything else becomes build time.

The biggest mistake people make is letting one thing mentally leak into the other. Startup anxiety during study sessions. Academic guilt during work sessions.

That destroys focus.

I use Obsidian heavily for context switching. When I'm studying, only study-related things stay visible. When I'm building, I fully switch environments mentally.

Some resources I'm using: DC Pandey for Physics, Cengage for Maths, NCERT + N Avasthi for Chemistry.

But honestly, systems matter more than resources.

The real trick is understanding that neither track tolerates half-effort. If you're attempting both, you need dedicated blocks where each gets complete attention.

Otherwise you just become mediocre at two difficult things simultaneously.
