B.Tech

You can surely do that in LPU. I personally did quite same. My branch in Diploma and B.Tech is different. And there is no question asked in LPU for that. Also, it is great to know that you did a Diploma and trying to apply for B.Tech, as it is the best way to pursue your graduation. Also, there is a special treatment for lateral entry students in LPU. When you take admission in LPU via lateral entry you will be with the lateral entry students only so that you cope with all the things in LPU. Also, the LPU NEST fee was waived off (for first attempt as per 2017 batch), which you can give as per your Diploma and 10th score. LPU NEST fees need to be paid by the normal students.

Hello,
It is very nice to hear from you that you are working professional and is now desirous of completing your engineering degree. Here I will like to add a word of caution. UGC has directed all universities to stop offering professional courses under distance mode of education. Hence this route is not for you. But yes, in the place where you are living presently if there are engineering colleges present and available you need to approach the administrative staff to find out which of these colleges offers part time courses. It differs from college to college and the way it conducts the classes. They also will tell you about the fees which they charge and the total duration for which you will need to study. Best wishes to you.
