hi,

see if the exams is on same date and same time, you need to attempt only one, if your college is in goa and center is not in goa area then it may not posible to attempt cgpet by osmania university, another thing is college exam is very important, unless you give the final exams then your provisional certificate issue of date will be late, agin you may need to wait for another 6 month, college passed certificate is more important for admission in mtech as well as job opportunity.
