You can apply in almost all the b-school while you are in the final year of your graduation. For filling up details you can enter your CGPA/percentage of the last semester. Details of the results which have been released in your college till the time you are filling up your details are acceptable. You can submit the final grade sheet before joining the b-school.

Remember one thing that generally in almost all good b-schools graduation percentage cut-off is 50%. So, make sure you are eligible before applying to any college.

All the best!!
