Hi. Yes, you can prepare for KAS exam if you really want to. Study everyday for 2 hours, it will be manageable. Also, the eligibility requires that candidate must have a graduation degree. So, you can start preparing along witht the studies.

Thank You!

It depends on interest of student .
Yes Engineers have more free time than medicos So as per time , it's good for them to prepare and this is what happens  . Civil services are cracked by more engineers than doctors  .
It is always manageable .
Thanks
