For MICA's GE-PI process, two test-scores are always considered before they shortlist any candidate. After that, you should clear any of the following- CAT; XAT or GMAT. You must essentially also manage to crack the written exam of MICA itself - MICAT.
This might look and sound difficult and a rather intimidating task, that you have to go through two competitive level exams to get in. You would be able to keep track of the level of your knowledge via Logical Reasoning, Verbal Ability and Quantitative Aptitude. Therefore, you must understand that it is vital to chalk out a plan and a strategy.
Interestingly, MICAT comprises two different sections which are - Psychometric and Descriptive. This isn't a part of your regular CAT/XAT/GMAT. What's unique isn't the fact that this particular section sets aside students from MICA and B-school graduates.
Here's a brief overview of Psychometric and Descriptive sections -
Talking about B-school graduates is pretty straightforward. Once they are shortlisted, they would stick to GDs or else WATs as their second option. While MICA does this. It administers a group exercise checking the candidate's leadership, teamwork and creative side. And by the time you reach the PI, you would go through a number of different experiences.
The path to MICA is indeed difficult and intimidating at times, but if you have already made up your mind to reach there by staying persistent in your efforts, you would definitely be successful. Once you're there, your life will turn around for good.
