Yes, after completing graduation, you will be eligible for doing PG Diploma.

Hello Ashwaniraj,
To join this job-oriented course, you need 10+2 in Arts, Science, Commerce or any other field. A 3-year Diploma in engineering or other fields, from the State Board of Technical Education is also credible.

This may not be possible as your percentage is not that good so, it cannot be guaranteed but, yes you can apply. You may get admission.
Good luck.

Yes, you can take admission in engineering in any department.
Almost, all the colleges accept lateral entries, but a few of the most reputed colleges like IIT, NIT and VIT do not encourage lateral entry.

Just submit a self-declaration stating a suitable and valid reason for the gap and you will be fine.

Dear Ronak,
Yes, colleges under Gujarat Technological University offers D2D entry in the 3rd semester of engineering colleges. Sardar Vallabhbhai Patel Institute of Technology (SVIT) is such a college that offers aeronautical engineering.
Hope this helps you.

Yes, you can. Approach the college without wasting anymore time. Admissions will close soon everywhere.
