Class 12-science

Hi,
BE in Nano Technology is a good option, but remember currently for 4-5 years, there are very less scope in India, because currently India don't use Nano Tech in every field, but better options are available in USA.

If you really want to apply for repeat Science boards, then you have to wait until the october-november, so that the examination form will be open. It will be beneficial for you to score marks. All the best for future.

Dear,
None can ensure about getting job in any field in our country. However, after doing this course your possibility of getting job in the specialized field is enhanced.
Best wishes.

Please specify which UPSC exam do you want to appear for as there are many types of UPSC exams.

Well, all the fields have their own scope and space of work and opportunities. Choose the area of specialisation you are interested in and good at. In my personal experience, I have seen how engineering is one of the really good and prosperous courses to pursue with good job offers and diverse career path. Alternately, you may consider Bachelors in science with subjects like chemistry, biology, mathematics, food technology, agriculture and biotechnology. Corporate and educational sectors; private and public sectors all of them open arms with job offers.

If you had taken up sciences in 10+2, then engineering or medicine or Bachelor of sciences (Physics, Chemistry, Mathematics, Computer Science, biotechnology, IT, electronics etc. In various permutations and combinations of subjects) or even BCA. These are some obvious transitions.

Yes, of course you'll be eligible to do that. You just need a Bachelor's degree for UPSC. Be it a 4 year programme or 5 years.

Hello Dear, You have just completed 12th. You will have to go for graduation. So don't make a time table for UPSC now. Whenever you get some time, do revise all the topics of History, Geography, Political Science that you have read in your school. Now come to the current affairs section. Do read some newspaper, read the important exam oriented issues. This will definitely help you to score a good mark in UPSC.

Hello Dear, Recruitment for IAS and other all India Services is done through UPSC civil service examination. For UPSC you need to be a graduate from UGC recognised institutions.
