B.Tech

GLA University is best for B.Tech from sage University. Apart from studies if we see the college placement rate is 70% from the past few years. 2300+ placement offered by the college in 320+ MNCs to batch 2019 to B.Tech students overall 1200+ companies visited the campus whereby 17000+ placement offered with the highest package offered was 32 Lacs pa. key recruiters are Amazon, Microsoft, Wipro, tata consultancy services, HDFC bank, Indiamart, etc. The university has been doing great every year to give its students a good future. And if you compare the fee structure of GLA to some other universities then it is not at all higher than what it is giving in return to its students. I recommend doing B.Tech from GLA university.

Hello! Ramitha G,. Madras Institute of Technology or MIT is affiliated to Anna University. Universities invariably offer degree of BE and institutions like IIT offer B.Tech. But let me assure you that, it makes absolutely no difference in your future life. For all purposes, both degrees are treated equally by the Industry as well as the academia. I would strongly advise you to not lose sleep over this totally insignificant issue. What is most important is the quality of faculty and perception of the institution outside it's premises. On this count MIT scores handsomely over its peers. Another issue you should not bother about is whether it's aeronautical engineering or aerospace engineering. Practically both are same. Best wishes to you.

Yes in some institutes and No in some institutes, it's possible to study M.Sc. In Physics after B.Tech in Mechanical Engineering. But only few colleges are giving chance for B.Tech students like Delhi University. Do some research about colleges giving this chance and join accordingly.
You would only be accepted to a few institutions if you wanted to pursue an MSc in physics. Traditional universities will not even accept you for a master's degree in physics. Furthermore, btech mechanical engineering is solely based on basic classical mechanics or lower level classical mechanics, the majority of which is newtonian mechanics.
BSc physics is focused on quantum mechanics, and almost all areas of study in BSc physics use quantum mechanics like there isn't any newtonian mechanics in the universe, so whatever they would be thinking in India about degree equivalence, a BSc physics is way higher than a btech mechanical engineering in terms of theoretical knowledge and depth of physics and mathematics, in fact, a BSc physics is way higher than btech, So, if you get into one of those select few universities, you'll have to work extremely hard or you'll end up in hell. Also, if you want to study physics overseas, a btech is ineligible for an MSc or MS in physics. Only those with a BSc/BS in physics are eligible. As a result, you won't be able to pursue an MSc in another country because their qualifying standards only allow for BSc/BS physics.

Hello Sayak Pal, it is very nice to see that you are interested in pursuing post-graduation in aerospace engineering. It is perfectly feasible and possible for you to achieve your goal. For this, you will need to appear for and clear the paper for aerospace engineering in the common entrance test for postgraduate studies in engineering called GATE. Here there are different papers for different subjects and a student is supposed to choose the subject in the which he or she wants to do post-graduation. For you are help and benefit I am attaching a link that will give you all the required information. I am sure if you study well, you can clear this examination and then complete yours are post-graduation in aerospace studies. https://www.shiksha.com/engineering/gate-exam
Best wishes to you.

You can do Masters in psychology being a B.Tech CSE graduate. It's quite easier to switch now to Masters psychology. Get ready to do hardwork since you are not a psychology background student. Few colleges won't allow non psychology background students, check before and join accordingly!
Without a bachelor's degree in psychology, you can pursue an MA or MSc in psychology. The eligibility requirements will differ from one university to the other. Many leading colleges provide an MA in Psychology to graduates with a 50 percent graduation rate. So, if you have a B.Tech with a grade point average of greater than 50%, you can apply.
Some colleges grant admission to courses based on their degree grades, while others grant admission based on their entrance exam rank. In addition to the written test, some universities will conduct an oral examination. Almost all major institutions offer this subject, which you may research on the university's website.
