i can only arrange around minimum 5lakhs of fees for mba suggest me wat entrance should i write and wat college should i apply

There are very good colleges at your budget preference lkke JbIMS and sydenham where fees are less than 3Lacs for two year duration. You need valid CET score with more than 99.7 percentile to crack above two colleges as there are less than 130 seats for MBA program and apllicants are 1000+. Moreover, you should apply for MHCET exam scheduled in February 2018. Start preparing for the exam from books like Chandresh Agarwal and Notes By CETkjng Coaching Classes. Make sure you give atleast 5-8 mock tests.

It is not about fees. You should aim to get the high percentile with national exams so that you get into the private/govt institute you wish too and most of the management universities have less fees so do not worry about the fees.

There is education loan also provided in most colleges.
