do we have enough time to prepare for cat from now onwards

Hi Aditi Mittal,
Yes, you have. It is better to start now than never. There are students who started preparation in September and made it to top IIMs. Try to give your best for next 4 months and leave the rest.

yeah why not if you have determination so it can be cracked .

you have approx. 2880 hours till CAT 2022, if one tries hard enough, then yes, one can!

it depends, how new you are to the syllabus.
