Hi Akshay,

Many of the diploma holders choose to pursue Btech in the same branch after completing the three year course. There is a lateral entry to the 2nd year of btech where the core subjects are taught.

List of Engineering Lateral Entry Entrance Exams

• AIEEE All India Engineering Entrance Exams
• Calicut University Lateral Entry Entrance Exams
• Delhi technical University Lateral Entry Entrance Examination
• Kerala University Lateral Entry Exam
• KIIT University Lateral Entry Entrance Examination
• Lateral Entry Entrance Test LEET
• LPU NEAT (National Engineering Aptitude Test)
• MIT-Manipal BE Lateral Entry Entrance Exam
• Mumbai University Lateral Entry Entrance Examination
• Punjab Technical University Lateral Entry Entrance Test (PTU LEET)
• UKSEE B.Tech (Lateral Entry) Entrance Exam
• Uttarakhand Technical University Lateral Entry Entrance Test
• West Bengal University Joint Entrance Exam for Lateral Entry (JELET)

If you have a valid score in the lateral entry exams you can get admission in a good college offering distant education. Some of the top colleges that provides btech distant courses are:

• AMU - Aligarh Muslim University
• Zakir Husain College of Engineering and Technology
• Wisdom School of Management
  
• Karnataka State Open University etc

Hope this helps.

All the best for a bright future !!!
