CBSE 12th

Hello Aarati,
There are plenty of opportunities after 12th. It all depends on what you wish to do. You can think of doing M.Sc in one of the subjects if interested in teaching. Join DRDO if interested in research. TIFR offers very good opportunities in physics.
What your heart desires? Do this.

We cannot predict what will happen by 2023, but with some ideas I can suggest you to pursue B.Tech in ECE branch because in coming years there are many ECE based companies which will visit India and consequently there will be high demand of ECE graduates.

You can appear for MBBS entrances or agriculture exams and at last biotech and pharmacy are the evergreen branches.

You can go for animation and multimedia as it has good scope.

There are many courses after completing 12th standard.

It totally depends upon your interests.

For CA it is better if you have maths, as to pursue CA you have to appear for an entrance called CPT which includes the syllabus of 11th and 12th along with maths subject.

A B.Tech in computer science and engineering will put you into the orbit.

Dear Adil,
You have to select your subject stream on the basis of your interest of subject. If you are from bio stream then go for medical course, if you are form maths then go for engineering, if you are from commerce then go for BBA and if you are from arts then go for arts courses.
