can a JEE topper share his/her notes?

Yes ! Why not ?

He will definitely share his jee notes to any relative or friend or someone.

There is no remarkable difference between his and your notes.

I do not know much about Aman bansal, but I had seen notes of Satvat Jagwani when I was in Kota.

The boy who showed me his notes was one of Satvat’s relative.

But, one thing I observed in Satvat’s notes proved that Satvat was a genius… Hats off to him.

• He has done long-long solutions in a very short space.
• One NLM free body diagram in just 2cm*2cm area.
• The solution which take the entire white board twice by a JEE teacher, Satvat can do it in the free space of JEE paper very effectively.
• His score was ultimate, but if we have a look at his paper, we will find it just neat and clean.
