Hey,

Yeah absolutely you can change your branch or college after first year. I’ll explain both below:

Branch:

In many engineering colleges the syllabus of all the branches in first year is approximately same. They do it so that student can have a overview of all branches and if they find that the branch they took is not their cup of tea, students can change it after the first year. There are some factors on which you will be shifted. First of them is availability of seats. If there is a seat available in the branch that you seek then there is a chance that you will be admitted to that branch. Second factor is your percentage, some colleges are having minimum percentage requirements if you want to change your stream if you are fulfilling it then you can easily change your stream

College: 

Student can also change their college after first year but they can only go to a college which is under the same university as their present college. Then you only have to take migration certificate any you can move. If you want to go to a college which is under another university then there are many problems which you will be facing firstly you have to take NOC and migration certificate from university that you are studying in. After that when you go to new college they will cross check the subjects that you studied in your previous college if there is any subject(of first year in your new college) that you haven’t studied in you previous college then they will show your backlog in that subject and you have to clear those subjects. Moreover some colleges also will ask you to pay money for the first year if you want to take admission in second year.

All the best
