Hi there,

Yes you can apply for engineering colleges even you have done diploma or any other course.

See, the basic demand of btech course is an individual must have completed class 12th from pcm group with a minimum of 60% marks.

Taking about lateral entry examination,  an individual  can easily apply for this and they can start studying right from 2nd year in btech.

So, it is quite good as well because you can hold two different degrees.

See, there are no such boundations due to which a student can not apply or can apply, it just depends upon you.

I hope this information will help you. Revert in case you have any doubt.

Thank you and good luck:)
