At IIIT Guwahati the curriculum followed is the same as IIIT H which is one of the best institutes for CS in the country. So, even if you are completely new to coding, after the completion of one year, you will be able to understand and do advanced coding. Provided you are passionate about coding and put in the required effort.
I have a few friends at the institute and according to them, there are many students on the campus who practice coding. The institute also has a coding club and a robotics club.
Also, the institute is still in the developing phase so you will get ample opportunities to collaborate on various projects with the professors, brush up on your coding as well as management and leadership skills. During YUVAAN IIIT G Cultural Fest, coding gets very intense among students.
