Science

Well, when you opt BE IT, it is a 4 year engineering degree course. It is purely a separate branch of IT in engineering colleges. It deals with very in depth knowledge about IT mainly, technological based.
BCA is a 3 year graduation course. Mainly dealing with computer operating and programming. You can say software part.
B.Sc IT is also a 3 year graduation course, which is more theoretical about science involved in computer and its part. Not software portion.
According to my opinion B.Tech or BE will be a good option.

This is a very open ended question and from my point of view, most important thing for you is to contact a career counselor and understand what interests you and get aligned with your interest.
There are several options these days and there is no dearth of opportunities, right from entrepreneurship to pure sciences to professional education such as engineering or medicine. There may even be possibility of changing the stream from sciences to commerce or economics. Therefore, most important is to figure out what interests you and pursue it with full commitment and passion.

There are many courses around i.e. CISSP, CEH etc. but I recommend you to complete graduation in either BCA or BSC-IT as companies are sometimes rigid about minimum academics.

Hi Puja,
Poznan University of Technology, Gdansk University of Technology and Warsaw University of Technology are the top universities in Poland for Master degree in Robotic Science. Please check the university website for more details.

Hi Gurman,
Most of the universities will count it as work experience but not all. You must check with the universities directly. Also, check for 15 or 16 year education work experience. If a college asks for 16 year education, you must do an additional year of academics in India.
I hope this helps.

I think you should join a production job immediately to gain some experience. Any number of academic qualifications do not bring an equal advantage. Work experience is valued more and perks also increase.

Hi Rajpal,
Which is your preferred country? I may give you correct details if you can clarify. You may also check QS university ranking or Economic Times and even Times Higher Education to view the best universities country as well as subject wise. Admission process is dependent on the country and university choice. High education grades are required besides other requirements which is a variant.

Yes there is stats and maths are there but college have best faculty for these subjects.
so all stream student are comfortably able to do. As you are from BA backgroud you have to work hard on it.
