What should one do once after receiving the cat score or result?

Hello Aspirant, hope you are doing good.

So, now that you have received your CAT score, and you haven't mentioned whether you cleared the exam or not, i would assume both the cases. In case you failed to clear the exam, you can either apply for other jobs , or you can prepare another year to reappear in the exam.

Now if you cleared the exam , you have to begin shortlisting the colleges that you want to get into, and start preparing for the next rounds of selection in your desired institutes. Like for example, if you are wishing to get into IIMs, after clearing the CAT exams, you have to sit for their WAT( Written ability test) and PI rounds. After you are done with all that, just wait for the results and see which college you get selected for. And obviously, you should have some backup plans in hand, just in case none of that works out, like other exams such as XAT, MAT, TISSNET, GRE etc.

Hope this helps you. Good luck!
