Hi Rekha.

Greetings.

The syllabus for almost all the colleges are same or similar for the 1st semester in the same branch on engineering, be it an IIT or other private college. They teach the same subjects and have almost same chapters in them. They might differ in the division on chapters according to the semesters.
