Hi Kunal,
You have got a good score in MAT and you have higher chances to get selected.
Fill the application form online and wait for the first list of GP/PI.

Hi Muskan,
You can definitely go for the Diploma in Indian Institute of Business Management and Studies on the basis of class 12th results. You may find out, if they are going for some entrance exams and prepare for the same. Also, ask for the admissions as soon as possible, because it may have already started.

It is a good college with good studies, overall development and good placements. It has great exposure and is renowned nationally. Big giants visit and pick students for good packages.

Well, every college has a cutoff list on the basis of 12th percentage for admissions after you fill up the prospectus.

No, but you can get ECE, IT and EE.
