Diploma

If you do not have any personal constraints then lateral entry B.Tech chemical engineering is the best option for you. You may also evaluate doing AMIE along with job after Diploma in chemical engineering.

Hi Jaspreet,
You can apply under the SPP programme, check colleges like Fleming, Humber, Lambton, George Brown, etc. Your IELTS is fine except the 5.5 score as it is important that you meet the IELTS requirement to avoid a rejection. Check with the colleges if they can consider this score or I will advice you to retake IELTS.

NATA eligibility criteria 2017:
1. Candidates passed/appearing in 10+2 or equivalent exam from a recognised board with mathematics as one of the subjects (with 50% marks) is eligible to appear in NATA 2017.
2. The candidates passed/appearing in 10+3 Diploma with 50% marks (mathematics as one of the subjects) recognised by any state/central government can also apply.
I would suggest you to go for 11th, 12th and science PCM as it will take less time to become eligible for NATA. It will also open other options for you.

In my view, you should join B.Tech. For this, Jaipur is the best place for engineering. NIT-Jaipur is the best college. But MNIT does not prefer such kind of Diploma students. They take admission through JEE exam. So, you can try for SKIT, JEREC, Anand International College of Engineering College, etc. For good placement, flexibility system in choosing faculty, section, timing for class for a particular class and other axioms, you can visit the campus of Anand International College of Engineering, Jaipur. This college provide excellent faculty members, digital study classrooms, etc.

You have not mentioned the name of the college for which you are seeking advice.

Hello Saurabh,
After successful completion of diploma, you can seek admission in Aeronautical Engineering branch in Maharashtra directly in second year in any college. You will get admission based on merit.
