Diploma

Sorry Pardeep, 49% is too low. Not only for Canada but most countries abroad. A minimum of 55% is expected.

Hi Sahil,
There is a little difference immediately but in the long term you will require more certifications or qualifications for career growth if you choose PG Diploma. Also, these courses have different career outcomes so comparing MS and PG Diploma makes little sense. A MS is more into research and academics career. PG Diploma is a professional program so naturally you have to keep on enhancing your profile.

The minimum criteria of eligibility needed to be met for admission to the course are listed here.

Hi,
Yes, you can take admission in B.Tech by appearing in LEET exam of the respective university.
There are many colleges which offer lateral entry to Diploma students to complete their engineering. After Diploma, B.Tech is of 3-years.
And it has many benefits as compared to 12+ B.Tech.
I hope I've made myself clear.

Hello Rudra,
Yes, you can take admission on the basis of LEET exam organized by the government. You need to score more than 50% marks in your qualifying exam for being eligible for admission.
