SASTRA (Deemed to be University)

You'll get into SASTRA. But no one can be sure if you'll get the desired seat for your marks. It always keeps changing.
I suggest you take up any course and then slide to ECE after the end of one year.

Hello,
One should keep in mind that the All India rank matters when it comes to getting the required course.
Even if you don't get the required seat you can choose any course in the beginning and then slide to civil after the end of one year if you have a GPA of 9.

Hello,
Of course he is eligible, but it's uncertain if you'll get the asked for course. You can always select a course and then slide to the desired course after the end of the first year if you have a +9 GPA.

Both these institutions are highly reputed in India. So you can pursue it from any of these. The only thing is SASTRA University has more fees as it is a deemed university. So if you can afford it then it is better.
For Anna University your board examination marks are enough but for SASTRA your JEE marks will also be considered (if appeared only).

Hi,
Admission into Sastra University is based on your JEE and your 12th board marks combined.
A merit list based on the combination of the both the mentioned marks. If your AIR is anywhere between 500 to 800, you'll be able to get into the mechanical branch.
All the best!

Hi, that is an impressive rank! You'll get seat in both the courses with your rank. But choosing your branch should be based on your interests. If you are into how millions of megabits of data is transmitted across the world and if you want to know how your calls are getting connected to someone on the other side of the globe, ECE is your forte. If you want to learn about heat engines, working of a motor engine and stuff like that, mechanical engineering is your cup of tea.
Remember to always choose your branch out of your interests and not based on other things like placements and stuff.
All the best!

Being a brahmin will not guarantee admission in Sastra as the admission is merit based. If you have a JEE score of above 120 you can get admitted in Sastra. Stream 2 is difficult for you.

Yes, you can get but it depends on the trend. since you have got 98.3%, I think you have a very good chance of getting admitted through stream 2. If you have JEE score of 150+, you can get in through stream 1 also.

Hello Niharika,
Yes, you can get admission as your scores are really good which gives you a high chance for getting a seat. I think you can get electronics and communication engineering. Your percentile will be 97.7(0.75)+56(0.25)=87.275. On this basis you will be placed on a rank.
All the best!
