I believe you can get a freeship too at this score. Most importantly, you scored when it was needed. Now forget everything which happened.
Code your ass off. Maintain a good GPA. It is easy to score 9+ in CSE at Manipal. This will help you to prove in future interviews that you have truly realized the importance of hard work.
Your past scores are only going to hurt if you change your mind for an MBA later but that’s irrelevant to your query right now.
You’ve got a great chance now. Make the most of it.
