CBSE 12th

look one has to give up something to gain something. And education is that precious thing which can never be compared to money.
Still due to various reasons ,i try answer your question in a mannerfull way.
firstly it depends on your INTREST and your 12 STREAM
if you want a brighter future then go for graduate field like engineering Bcom MBBS etc. trust me the salary you can attain can be thousands of times your dream salary and your personal satisfaction in particular field.
otherwise, teaching line or diplomas are waiting for you which i think can't meet your wishes as put in above question
Also, don't forget to file for competitive exams and jobs for both private and govt sector.
good luck

Hi Nikunj,
The options are unlimited, as you have done your class 12 with science. With a PCM combination of subjects, you can pursue almost any field you set your mind on. You can ofcourse do Engineering which is a professional degree and has streams such as Electrical, Mechanical, Electronic and Communication etc. You can do your graduation in subjects of your interest, even switching to Humanities or Commerce streams if you so desire.
Apart from doing the degree level courses in science with the conventional combinations you can also choose degree courses in several emerging professional areas, such as computer, business administration, hotel management, tourism management etc. you can also opt for courses outside the university stream, such as hotel management, fashion technology, industrial design, packaging, aircraft maintenance engineering, government accredited computer courses and a host of post 10 + 2 level vocational courses. For pursuing a course in engineering you should have Maths as compulsory subject in 10+2.
You can do a BCA (Computer Applications), BBA (Business Administration), Law, Civil Aviation – Pilot, Astronomy, Architecture, Design, Mass Communication, Merchant Navy, Defense Forces, Psychology, Civil Services etc. To decide on the course, you should analyse your strengths, career goals, interests, personality, aptitude and ability. If you decide based on these parameters you will put in your best effort and will be successful in your chosen field.
Hope this information helps. Please feel free to revert.
Wish you luck.
