Hello Aspirant...

Hope you are doing good...

you said you have messed up with your JEE 2022 preparation and you also said you did not study any thing for the exam. the exam dates are released and the exam will be conducted in june... there is a time of around 45 to 50 days. if you are confident that you can clear the exam with what ever preparation you have and what you can study in the remaining time...you can give your exam. there is a chance that you can crack the exam so just give it a shot. even if you do not crack the exam you will get an idea as to how the paper will be given and just hope for the best. there are some other colleges which offer seats based on the rank you got in the JEE. so just hope for the best try to give the exam.

hope this information helps you...

all the best.
