Yes, you can pursue B.Tech through lateral entry after completing your diploma in Computer Science, as lateral entry admission generally requires a Diploma or equivalent qualification in a relevant field.

Here’s the breakdown:

1. Lateral Entry to B.Tech:

• Eligibility: To get into B.Tech through lateral entry, you need to have completed a 3-year diploma in a relevant field (like Computer Science, in your case).

• Admission Process: Most universities and colleges conduct lateral entry exams or accept lateral entry students based on merit from your diploma. Some institutions might have their own entrance exams, while others may admit students based on the marks obtained in your diploma.

• 12th Marks: For lateral entry admission, your 12th marks are generally not a primary factor. The focus is more on your diploma performance (aggregate percentage and relevant subjects).

2. M.Tech After B.Tech:

• Eligibility: After completing your B.Tech, you can pursue M.Tech in your chosen specialization, such as Computer Science or any other field. You need to clear an entrance exam like GATE (Graduate Aptitude Test in Engineering) for admission to M.Tech programs.

• 12th Marks: Your 12th marks will not impact your admission to M.Tech after B.Tech. Admission to M.Tech is based on your B.Tech performance and GATE exam scores.

In summary, your 12th marks won’t play a significant role in lateral entry for B.Tech or M.Tech, as the focus will be on your diploma performance and subsequent B.Tech exams.
