Hey student,

You have scored really well in your exams and congratulations on that. You need not worry if you have got 87% aggregate because there are universities which consider only the marks in your best Four subjects. You can exclude mathematics from your best four until and unless you want to graduation in mathematics.

And even if you have to include mathematics, 87% is a good enough score. You can appear for entrance exams and get admission in course of your choice.

I hope this information helps you.
