hi !!

I did my 10th with 72% in 2000, my 12th with 63% in 2003 and again did my engineering from 2005 to 2010 from private college with 65% aggregate (again one year gap due to health).

i joined a automotive firm in 2010 and till the date worked for US, Japan and Europe based MNC's.

Now at this stage after more than 3 years of Experience i eagerly want to do MBA from reputed college of India.

i am very average student for the shake of Maths as well as English. in my academics there were too much irregularities due to my health problems.

but with all this i am ready to do hard work for shaping my carrier better, so please its my humble requests to all experts exist on this forum please suggest me for which exam i should appear and how to start from zero.

And one most important doubt, presently i am working with an European MNC. i am able to spend three hours per day in working days and free on Saturday and Sunday completely, so for preparation should i quit job or available hours are sufficient for me. (considering an average student).

trillion thanks in advance !!!!!
