hi piyush

hope you are doing well

don't worry and work hard . Hard work will never let you down. Btech mathematics is not at all difficult .It is a myth that Btech maths is tough. The mathematics syllabus varies from university to university but generally it is easy and you can score good ,marks if your basics are clear

But the thing is that yes it is a degree course which is quite difficult to pursue because it requires a regular study and the student must be completely focused on the subjects and innovations that are taking place every day with the advancement in the technology .

all the best
