Hello Muralikrishnak,
Since you are new to the city of Manipal, it might take some time for you to get adjusted with the environment and surrounding. Also, no worries if you have issues with their mother tongue, you can always communicate in Hindi or English with the people around you. Also, to get a job it is expected that the student shouldn't score below 60%. Therefore, it is absolutely alright if you scored 61% without any backlog in any of the subjects. Try scoring better next time by working hard. Ask for doubts to the teachers and get it cleared. Study on regular basis. Make sure you don't go below 60% and that you do not have any backlog.
Good luck!
