I didn't study computer science in 11th and 12th grade, but now I wish to pursue computer science at the Manipal Institute of Technology. Is it a good decision to do so?

Even I began programming at Manipal Institute of Technology itself. I didn’t opt for Computer Science during 11th and 12th. 

In the first few months, you’ll find a gap between those who can’t code and those who already can. The first few lectures will be quite difficult to understand. During your three hour lab sessions, you’ll struggle to complete the assigned programs on time. On the other hand, there will be students who will complete the same task much faster. You might even score less in the first few tests. 

Now after all this, you’ll feel disheartened and approach people for help. Many will misguide you towards a branch change. This is when you have to choose- either you run away or face your fears. You’ll have to work hard and learn programming.

Do plenty of reading, approach your faculty with doubts, and seek help from friends who know programming. Manipal provides a good learning environment. It’s just that you’ll have to exhibit a lot of patience and hard work. 

Pursuing my CSE from Manipal was the best decision I made. If you follow my advice, by the time you graduate, you’ll be at par with the rest of your batch.
