Hello Kulsum,
First of all congrats and yes you are eligible to take admission in computer science.

Hello, with this rank in JEE main you won't get a seat in any government colleges for engineering for sure. Actually all the seats get exhausted at around 50k, so please go for best private engineering colleges like Sharda, Amity etc. Please visit this link for more such colleges

Hello Aditi, It's a very loaded question and there is no straight forward answer. Reservation in government colleges has reached 60%. But then private colleges and deemed to be universities do not have reservations. Of course the major exceptions are colleges formed under minority category (linguistics & religion) which have reservations up to 50% for that strata of society. Best wishes to you.

Well brother in this case I think no one help you out except the college. So it's better that you should ask them and do negotiation. Best of luck.

I'm sorry to say that you won't be able to get in any kind of government college because until now no college has taken students with more than 3000 rank. I don't know about Haryana government colleges closing limit, but if you want then you can apply there.
Best of luck.

No, chance at this rank in JoSAA counseling.

First of all, in India, the aerospace division lies in the government sector. So, for admission in those govt. companies, you need to go for competitive exams after graduation. Government companies are DRDO, ISRO, HAL, etc. Secondly, you may get placed in the educational sector.

B.Tech has much more weightage than BCA. But B.Tech is also costly and a year-long course than BCA. Which is not suitable in your case. BCA and B.Tech both the courses will provide you with the platform to get started with programming but they might not teach you exact ethical hacking. It is something that you might have to do on your own from external institutes.
