With **GATE score 534 and AIR 2362 (General)**, admission to **top IITs/NITs for Microelectronics** is unlikely. You may get seats in **state universities, private institutes, or less competitive M.Tech colleges**, but **BITS Pilani Microelectronics is very unlikely**.

Why b.tech completed students not eligible for TET or DSC? B tech education is more than diet education

In most Indian states, just having a BTech degree is not enough to appear for TET or DSC. You usually need a proper teaching course like B.Ed or D.El.Ed along with it.

This isn’t about how “big” or “small” your degree is. It’s about teacher training. A BTech gives you technical knowledge, but it does not train you to teach students in a classroom. That’s why, even if BTech is a higher degree, it is not considered a teaching qualification. States want teachers who are trained specifically for teaching, which is why they insist on B.Ed or D.El.Ed.

So, if …

Dear Student,

Yes, as an agricultural engineer with an MTech in Soil and Water Conservation Engineering, you can apply for many PSU jobs through GATE Civil Engineering. However, it depends on the specific PSU, the post, and whether they accept a Civil Engineering GATE score for agriculture, water, or environmental roles.

Most PSUs require:
