low students appear in jee main is good or bad ??

Dear Aspirant,

I think you mean that students who are academically less intelligent or who have a poor background giving JEE Mains.
Honestly, it doesn't matter of you are rich or poor. If you have the talent and zeal to crack the paper, you are good to go.
On the other hand if you are academically weak, then you need to work on your preparation standards as it's a competitive exam. To grab a good branch at a good college you need to level up and work hard.
In my opinion no one is weak in studies, you just need to stay consistent and make sincere efforts.

Hope this Helps!
Good Luck
