To pursue TYBA at Mumbai University, you would need to:
1. Complete your SYBA at Pune University: Finish your second year at Pune University and obtain your marksheet/transcript.
2. Apply for TYBA Admission at Mumbai University: Once you've completed your SYBA, you'll need to apply for admission to TYBA at Mumbai University during their admissions cycle. This will involve meeting Mumbai University's eligibility criteria, which might include specific minimum marks in SYBA and potentially other entrance examinations or interviews depending on the college and subject. It's crucial to check Mumbai University's official website for the specific admission process and deadlines.
3. Credit Transfer (Highly Unlikely): Mumbai University *might* consider credit transfer for some subjects, but this is highly improbable and depends entirely on their policies and the alignment of the curriculum between Pune and Mumbai universities. Don't count on this; it's best to assume you'll have to complete the full TYBA program at Mumbai University.
In short, you can't directly transfer. You must complete your current degree at Pune University and then apply afresh to Mumbai University for TYBA. Contact Mumbai University's admissions office directly to verify the admission process and understand all requirements.
