Technically yes and no at the same time.

Yes, because you can change your college in 2nd year.

No, because if you change your college, then you won't be enrolling in a normal BTech program in IIST Indore. You would be enrolling under BTech Lateral since you are in 2nd year and you can get entry through JELET.

Straightforwardly, you can't just hop on in a class of 2nd year BTech CSE at any college if you wish. You can get admission but it would be at a cost, i.e. BTech Lateral.
