How does Maharashtra MBA/MMS CAP work from registration to admission?

Registration: fill and submit the online application form and upload the required documents. While filling the form, choose one document verification mode: E-Scrutiny, where your documents are verified online and you need not visit a centre, or Physical Scrutiny, where you visit the Facilitation Centre you selected with your documents.

Merit lists: a provisional merit list is displayed on the website. If anything in it is wrong, raise a grievance within the grievance period; no documents are accepted after the scheduled dates. The final merit list is then displayed. The merit list shows your relative position but does not guarantee admission.

Option form: before each round, the seat matrix is published. Fill your choices of institutes and courses in decreasing order of preference — up to 300 — and confirm the form through your login. Filling the option form is mandatory to take part in a round, and once confirmed it cannot be changed.

Allotment and acceptance: the provisional allotment for each round is displayed. To accept your seat, report to an Admission Reporting Centre (ARC) or do self-scrutiny of your uploaded documents online, and pay the seat acceptance fee. Only then report to the allotted institute to take admission.

Freezing a seat, betterment in later rounds and cancellation are explained in the question on options after allotment.
