You can choose any field in MBA if you are interested in.
But as you are interested in a mechanical engineering related field, go for Operations Management as they are dealing with the production, quality and supply chain in the industrial area.

For CAT 2020, you can join any reputed coaching center in your city and start practising daily. Focus more on CAT in your last year. You can join test series in the last few months before the exams. That will help a lot. And if there is no good coaching centre for CAT, join online coachings for CAT as there are already a lot of online platforms available. You can learn from lots of YouTube videos according to topics.
Best of luck.

I will suggest you go for both of those exams as CAT and MAT are the entrance exams preferred by most of the MBA colleges. If you perform well in at least one exam, there are very good chances of getting a good college. The syllabus for both the exams is not that different.

Neither BBA nor B.Com provides direct placement. If you want to pursue MBA, then BBA is the best and MBA has a brighter future. If you want to go for the teaching line, you can opt for B.Com and M.Com for CTET and UGC NET.
All the best.

No, MBA course is available in English only and that should be in English as English is an important language for any managerial job.

If you are getting any top-reputed college through UPSEE, then go for it as you already have a good rank.
Don't waste one year for CAT and MAT. That would be a risk if you do not score well.

At this rank, you can get good colleges. For that, you have to wait for the 3rd counselling round. After that, you can get a good college of your choice. In IPU, some of the colleges at this rank which you can get are:
Northern India Engineering College
Rukmani Devi
