B.Tech

Its better to explore your knowledge and information in India itself than going to other countries. It's a booming industry nowadays and many startups are coming in picture. So, try for that and get into it.

From my point of view, Thapar University is very much better for placements. So, work hard and achieve the best.

B.Tech -CSE from JIIT Noida will be better than one year drop. The reason is quite simple that there are majority of people who join JIIT Noida after taking a drop. So, you need not to take a drop then.

There is no minimum marks criteria for applying in JIIT Noida. It solely depends on quality of applicants applying for admission here. Flipkart visit JIIT Noida for placements.

For B.Tech-CSE, JIIT NOIDA has much better average placements statistics. Prefer it over USICT.

Dear,
If you are a BE or B.Tech student and want to go in mathematics, then it is not much difficult task. JAM (Joint Admission test for M.Sc) is very useful for us. If you qualify this exam then after BE/BTech, no need to do MSc. Directly go for PhD.

Yes, you can join. Many colleges gives chance to student from other streams with different graduation degree to do their Masters in design. The colleges will teach you from the basics. So, it won't be a problem for non designers.

VIT Chennai offers 5 years integrated M.Tech programme in Software Engineering. The end criteria is given under:-
Eligibility criteria :- A candidate should have passed in Higher Secondary Examination conducted by the state / central board of examination or its equivalent examination with 70% in Physics, Chemistry and Mathematics (PCM) with an aggregate of 75% marks for general and 60% for Sc/St categories.

I think, you can't do this. There is a huge difference between CE and civil engineering
CE is completely technical field.

It's quite good, There are respectable alumni who graduated from there, Moreover, it is quite good as per return on investment. So work hard and achieve the best.
