Dear Aspirant,

If you have not yet started your preapration and you are aiming for JEE 2020, January attempt, then you will not be able to get good rank in your exam. The minimum time needed to prepare for JEE is 1 year to get a good college and for IITs, this might be even greater than 2 years.

However, you can aim for April attempt. The form will be release in Feb 2020. In that attempt, you can at least get a rank under 1 lakh if you prepare decently and then you can join some state funded colleges.

Hope this helps. Thank you.
