Hi Mega!

Since you are Lateral Entry Student, you can join Engineering Course during the Second Year! Like regular Engineering Students will have 4 years of Engineering Course, during their Second Year you can join as a Lateral Entry Student. The marks scored by you in your Diploma will be considered for your Admission in Engineering Colleges. Maybe through Counselling or any other Processes the respective Colleges follow!

Hope this is helpful!

All the best!
