Hello Aishwarya,
Yes, Pradhanya is a good publication. There is no shortcut to success. You have to make schedule & timetable for studies covering all the topics. Then take weekly mock tests. Brush-up on weak areas. VJTI, ICT and COEP are few of the best colleges in Maharashtra.

You can go for an integrated MBA (BBA+MBA) course at IIM, Indore.

Hi Mk Raghav,
Study abroad is a vast term. You should mention the country for proper guidance because every country has a different process and requirement. In addition to the requirements, you must be good in your studies, complete your 10+2 with very good grades. You must also take English language tests like TOEFL or IELTS.

You can find a lot of MBA colleges, but you should be very cautious about choosing the best, and for that, you should look at few things like the college campus and infrastructure, hostel facility, placement cell with placement record, etc. I would recommend, you should opt for UEM, Jaipur to fulfil your requirement.
