Dear Swapna, are you talking about lateral entry into B.Tech 2nd year after Diploma? You haven't mentiones the stream that youbhave completed your Diploma from. There are quite a few colleges that allow lateral entry into B.Tech 2nd year. For example, Parul University of Technology has Lateral entry into B.Tech Mechanical stream for diploma candidates who have scored 50% minimum aggregate in Diploma from a recognised Board. There is a programme in Gujarat which is called Diploma to Degree conducted by ACPC which stands for Admission Commitee for Professional Courses in Gujarat. ACPC manages admissions into 2nd year Direct Admissions of Engineering. You can check more information about them at their official page: http://gtu-info.com/Gujarat-Engineering-Admission
