There is no difference some people call it be some b.tech

Dear Sai
First please note that there is no difference between these degrees in terms of value and scope. BE and B.Tech have smilar scope and future and on the same time ME and M.Tech have same scope future.

Now lets dig the question little deep. If BE and B.Tech or ME and M.Tech have same value and scope why the names are different.

Right after independence of India we have two types of universities, one that offers degrees in many fields like Sciences, Arts, Education and Engineering too, and the second set of universities (were named as institutes) offer only degrees in engineering. Universities those offer other degrees along with engineering named their engineering degree as BE (Bachelor of Engineering) and Institute constituted for only Engineering studies named their degree as B.Tech (Bachelor of Technology).

Now as AICTE approve courses most of the courses are same and identical for BE and B.Tech. The universities those offering BE when started new courses named them to B.Tech too.

No degree, BE or B.Tech and ME or M.Tech is superior other others in terms of theory or experiment. BE and B.Tech or ME and M.Tech are same. Both of them are same and have similar scope and future. If there is some notification for BE, B.Techs are also eligible to apply and vise versa.
Hope, my answer clears your doubt.
All the best.
