CBSE 12th

Hello Suresh Kumar,
Yes you can complete it by open schooling like NIOS. You can choose your date and time according to you. Also you will get your mark sheet very early.

Hi Pulkit, there are many courses to choose from. Firstly have clarity over your career and future plans. Ask yourself in which area are you looking for good job opportunities? Follow your interest, weigh your likes and dislikes, strengths and weakness and decide what is best for you. You may share your interests if you require further guidance. For now, take a look at the list of courses on the Shiksha homepage.

You have several choices such as a Bachelors degree in physics, chemistry or biology. Also, explore your interest and check if you would be interested to do a Bachelors degree in any of the following:
Psychology
Biodiversity
Biochemistry
Molecular Biology
Bachelors of Health Sciences
Bachelors of Nursing
B.Pharma
B.Sc in Agriculture and so on.

There are many courses you can do after your 12th with science stream. If you are a PCM student, B.Tech and B.E are the most popular courses students like to do after 12th.
If you are a PCB student, MBBS is one of the popular courses you can opt for.
You can also Do B.Sc Honors in your favourite subject (i.e Physics, Chemistry, Mathematics, Biology)
You can also opt for B.Sc in Agriculture, Hotel Management etc. as per your interest.
Alternatively, if you are not interested in science stream, you can also opt for commerce or arts& humanities courses like BBA, B.Com, BA, etc. courses are popular courses.
