B.Tech

Hello Karthik,
No, it is of course not necessary to do M.Tech for getting a job after doing B.Tech in Aeronautical Engineering, but the issue is not this. Issue is, in India, at the moment, the jobs in the core sector of Aeronautical Engineering are very hard to come by. ISRO, DRDO, armed forces are some of the recruiters who are requiring specialist from this branch but the Indian industry is still not requiring Aeronautical engineers in the numbers that are passing out. Due to this, many graduates prefer to go for M.Tech either abroad or in India or go for MBA and then get a job based on this new qualifications.
Best wishes to you.

You can get a direct admission through your JEE Mains rank or through your 12th percentage or you can give CUSAT conducted by Chandigarh University in the month of June.

Yes, you can. As per the eligibility criteria any student with a minimum of 50 percentage is eligible for an admission in Chandigarh university for B.Tech CS.

Compared to thappar University, Chandigarh University has a definitive way of curriculum and a highly tailored students placements training department which has made CU with an average package of 4.5 Lacs per annum while thappar University has 3.6 - 3.9 LPA.

It totally depends upon the overall admissions at end of the admission period and then they allot a definitive seat matrix for students ranging from 50 to 70 students per classroom.

As per the latest trends of coding world Chandigarh University teaches all the essential languages like C, C+, Python, Java, Net, Oracle, etc. as requirement by placement companies. http://www.cuchd.in/engineering/BE-CSE.php.

Yes, you can do. Since you studied biology in plus two. But Since you have done B.Tech think twice before you seek admission. But if you think nursing / health is your field then go for it.
Best wishes!

Evening/distance/online/part time engineering courses are not valid any more as per the latest supreme court verdict, hence would recommend you to join regular B.Tech course for better career prospects
