Diploma

No, it is not good choice to join 3 year integrated Diploma from SLIET, because it will take six years to complete you B.Tech degree after 12th.3 years for yours ICD course and after that 3 year degree (Lateral Entry).If you JEE Mains rank is not good look for other private college. If you still interested in this college join this college for 4year degree course you should easily get this college if your rank is nearly around 50k.Please don't go for ICD course.

You are advised to approach big civil engineering contracting firms doing Infrastructure building work directly for job after Diploma in Civil Engineering. If you open to relocate to small towns where infrastructure work is being executed, you will get job easily. If you are looking for jobs in big cities, then you may face lot of challenges.
