Well, there are many colleges for that, but it depends on you that how you collect your knowledge. Well, all IIT and NIT college scope and jobs are good.

Its' really hard as you haven't taken IT nor maths as your subject. So the only way to become a software developer is to study on your own and search institutes who'll help you out in this. Trust me, if you choose to do this it's going to be really hard for you. So, in my opinion you should look out for any profession.

Yes, definitely you can pursue the course with biology in 10+2 provided that you are also having physics and maths as your subjects. The fact is that biology has no role to play in software engineering, so it is better to take computer science subject in 10+2. And maybe in some colleges, they prefer students with computer science for the course.
Thank you and best of luck.

Yes, but you'll have to work hard on your skills. You'll have to learn computer languages like C, C+, JAVA ,HTML. Most of these are taught under college's syllabus and you just have to study them thoroughly.

You have following options to become IT engineer:
(a) B.Tech CSE / IT
(b) BCA-MCA
(c) B.Sc-M.Sc CS/ IT
(d) Diploma in Computer Science
(e) DOEACC Certifications
(f) Graduation degree with computer courses etc. You can choose any of the path as per your preferences and interests.

If you want to further study with your job, then you can choose distance mode course for further course. There are many institutes which provide distance learning in your field.

For fresher, it will be around 3 to 4 lakhs. If you have an attractive resume, it may be bit high then.

You have to do B.Tech in computer engineering or information technology from any good reputed college. I will suggest you to join any college in Bangalore that will be the best.

It's great to hear you didn't mention you want to do engineering instead. You can go for courses of NIIT, DUCAT, etc. They will introduce you to the world of IT better than any engineering college.
