Hello as aspirant.

As per your question i do understand your state of mind.

Your percentage is not that pow as you may think.

Most of the courses and colleges, government require you to clear a particular entrance exam.

You can get admission based on or off your merit list in private colleges.

Admission process is simple if you are going for a particular course like mrdical then you must clear NEET exam.

For B.Sc. there are exams required to clear.

All the best.
