Career

I'll give two cases for a analysis:
1)A person having good overall academic profile say above 90% in all 10th,12th and graduation and overall work experience of 4 years but he scored only 80% in CAT due to lack of preparation. He is never going to make into any of the top 5 IIM's.
2)A person who got average academic profile say 60% above and got 0 work experience but he scored 98%+ in CAT with thorough preparation, he is definitely going to make into one of the top 5 IIM's.
In India weightage given to overall profile is low and the CAT score is extremely high. If you think you can go with both CAT preparation and Work altogether then get a job otherwise be determined on CAT only. Don't worry for lack of experience. Trust me once you got passed out from one of the top 5 institutes you're gonna kick start your career no matter what you got.
All the best.

Anshida,
If you're creative, you can always consider going for Design and Animation. This is a field where nobody cares for your qualification, they only see if you can do quality work. In fact, the University Model has not succeeded in any Skill field across the world. A good mentor and wise selection of courses with a good school, followed by diligent learning, would get you a head start in your career.
However, you must check your suitability for this field. Animation is an art form and a very demanding career. It has ample opportunities for the creatively talented people. Opportunities lie in UI Design, Graphic Design, Storyboarding, Animation Design, Game Design, 3D Modelling, Texturing and Lighting, Dynamics and VFX and of course animation (2D and 3D). Of course at the top of the pile lies Concept Designing - these people are required by Event Companies, Animation Studios, VFX Studios, and of course Game Studios. However, choosing between these must be done after seeing your performance in each of these. So going for a generic course covering all or most of these would be the best way to get started in these careers. Typically you should have good sketching skills to be able to make a sound career in this (if you work hard you can improve your drawing skills tremendously).
Nothing but your innermost talent and passion should lead you to the course and the institute you choose. Go speak to people over there and see if you like their philosophy and they change your perspective. Try their website for more details. Also remember that Animation requires good mentoring. Typically go for a school which offers all the information including faculty on their website.

Wish you the best for your career. Remember, your Career is a resultant of your knowledge combined with your passion and expression ability. If you like this answer you may select it as best answer or press like.

It's very good that you have figured out what you want to do straightaway. Now you can focus completely on your goal and grow your career in the right way. Since you are interested in Android Technology I assume you have some programming knowledge. And if not then please start learning now and try to Master either C+ or Java.
Java will be my personal choice. After you Master a programming language, rest of the things will be pretty easier. Go for the new Boston videos. They are very good. After that go for learning Android programming from scratch. You can take online courses. According to your preference you can opt for any.
But along with that for now focus on your boards and crack the Engineering entrance exams and get in a good engineering college. Take computer Science branch and be the coolest Android Developer ever.
All The Best.
