Dear candidate, hope you are doing well.

Your improvement is really appreciable. Look you have two choices. First one you can take admission into that college and keep preparing for jee mains 2022 because in the first year of btech the subjects are same. And also in the first year you will get enough time for preparing. Another option is that you can take a break and prepare again also you can prepare for your JEE advanced. But according to me the first choice is better because there will be no risk. JIIT is also one of the prestigious colleges providing great faculty and infrastructure.
