Hello P.bharat kumar

I hope you are doing good . I would like to know you that the procedure in getting admission in foreign universities is very different then getting admission in universities of india . Like in india ,foreign university dont give admission to students based marks scored in 10to12 or score in ug . Though its marks are considered but percentage of consideration is very low .Admission are basically given to students based on their profile that what you will give to their university and their country . Following are the factors which are considered.

1. Letter of recommendation

2. Statement of purpose

3. Academics score

4. Work experience

5. Score of language proficieny test

Try to build your profile and aims for other universities if you failed to get admission in harvard , cambridge so that your year can be saved

Hope you found this answer helpful. Good luck for your future
