Hey Abhay,

"When there is a will, there is a way". Never loose hope if you started something which you can do not easily but definitely. In my opinion, you have to give JEE Advance because it will be good for the betterment of your confidence and as well as your result.. Work Hard and Smart and never loose hope.

In my opinion you can do better in JEE Advance so you should give JEE Advance because there is no meaning of JEE Mains results in front of JEE Advance, they both are different exams and also they have two different results.

Give your best shot and Hope for the best. Thank You !
