CMA

Yes. ICMAI releases the CMA model question papers for all subjects under Foundation, Intermediate and Final courses. Along with the questions, ICMAI releases the answers to all these question papers. Candidates can access the ICMAI CMA MQPs for better preparation of the relevant course. ICMAI releases the CMA MQP separately for both exam sessions, including June and December.

Adithya College of Arts and Science and PSG College of Arts and Science are good options, as they offer specialised B.Com programs with integrated CMA courses.

Yes after the completion of CMA (Cost management accounting) students can undergo various internships.

 However, the training typically lasts for 3 years after the intermediate level, but students can begin their internship immediately after passing the intermediate exams. The ICMAI provides guidelines regarding the types of organizations where students can complete their training (e.g., in a company, firm, or with a qualified CMA professional).

CMA June Foundation admit card will release a week before the exam dates. The Institute of Cost Accountants of India (ICMAI) does not release the schedule for issuance of the CMA admit card. The admit card is downloadable from the official exam website a week before the exam date. Since the CMA June exam is scheduled to be held in the second week of June, candidates can expect the release of the CMA Foundation June admit card in the first week of June.

Since you've registered for the CMA Foundation on a 10th passed basis and are currently in class 12th, you should wait for the ICMAI to release the admit card, which usually happens a week before the exam date. If you haven't received it by then, contact the ICMAI student support for assistance. Visit the official ICMAI website. 

Look for the "Admit Card" or "Examination" section. 

You'll likely need to log in using your registration number or other credentials. 

Download and save the admit card.

Yes you can go for B.Com while pursuing CMA but I personally suggest you to do B.Com online from Amity university as they have very comfortable facilities and excellent placement records for students.
