According to my friends who are studying at Pune University, there are question papers on the official website. But you won’t get solved papers for any year from the website.

If you want solved papers, you will need to solve the question by consulting reference books. There are also some online made easy solutions that you can look for.

I have a few friends from Pune University and here are some of the things that they complain about.

Name: First and foremost, there is the name. The name "Pune University" was well-known in India at a time, but not now. If a student walks into an interview with a degree from "Savitribai Phule Pune University," the interviewer has no idea that this is the same Pune University.

Administrative structure: With a few exceptions, being an Indian university has the same old administrative structure. Every time there is a delay in the examination results and everything else is official. The majority of the staff in all the university's offices are uncooperative.

Official website: It is extremely slow. Almost always, there is a server problem. The library's online portal never opens. Nobody will find the notice of their interest in time because the notices, events, and news section is so poorly maintained.

College campus: Despite being one of the greenest and largest campuses I've ever seen, the vastness overpowers the beauty. There are no proper directional signs. Every new student on campus often gets lost in the campus's maze of roads. If you just want a cup of tea, you'll have to walk for about 10-15 minutes.

Professors: There are very few departments where students are fortunate to have good teachers. Otherwise, the majority of teachers are not very good.

Curriculum: In comparison to other universities, the syllabus is not that good. Universities in West Bengal and Delhi, for example, have a much higher level of curriculum at the graduate and undergraduate levels. As a result, students from these areas outperform Phulites in competitive exams and interviews. In addition, the syllabus is also ill-organized.

These are some of the things that you need to know before choosing Pune University.

Ony of my sisters is a part of Pune University and as per what she mentions, it is best that you practice the fundamental mathematical problems. Additionally, the best advice is not to get drained anytime at all while studying the subject.

Now, when shifting focus to your question, 

• M1 incorporates basic algebra and is deemed pretty simpler than usual. 
• On the other hand, M2 might still be difficult, yet it can however be aced if you practice the basics of integration and derivation.
• In the case of M3, the course entirely depends upon the fundamentals you have earlier prepared for M2. 
• After a brief elaboration, it is best that you rather choose preparing for M2, because it can contribute to making the subject quite easier. 

The study standpoint is curated as per the syllabus, and is best if you follow the pattern in accordance with it. 

Based upon the department and subject choices you have curated for yourself, you can determine the depth of your preparation. For instance, if we talk about mathematics,

• Almost half the questions that arrive in the examination are somehow expected to be curated from Nirala Publication.
• For better preparation, you can simultaneously take assistance from similar tutorials for practicing assignments. 
• Other than that, it is best if you take the exam on paper, rather than on an oral basis, because that leads to depletion of your concentration. 

This is all that you need to know. Hope this answers your questions. You can try and reach the alumni of the college online to get better, more intricate details.
