UNIPUNE - Savitribai Phule Pune University (SPPU)

Hello,
Yes, you can change college or university without repeating first year.
For that, you have to secure good marks with no backlogs or kt and upto 75 percent attendance.
Thank you for considering my advice.

The Savitribai Phule Pune University (SPPU) has introduced an integrated Bachelor of Science (BSc) and Bachelor of Education (B.Ed) programme to produce quality mathematics and science teachers. The course, which has an intake of 50 seats, will begin on July 15. Someone said that the department has so far confirmed 25 candidates. No not any entrance exams only on the basis of merit

You can apply for PGDM at Welingkar.

Welingkar is the best option among these colleges and has a good brand value in India. PUMBA has a good ROI. Welingkar, Mumbai campus is an older one and preferred for management studies.

University change or college change after first year is completely dependent on the university and college norms. Some universities allow it and some won't plus you need to have good scores in first year to apply for the same. For further details, contact the university authorities.
Under the same university, it might not be difficult.

After MHCET scores are announced around month of April or May, you shall receive notification for admissions in MBA and MMS courses, for PGDM, dates shall be announced soon.
