CBSE 10th

No, very sorry. They will need IIT-JEE scores.

Hi Aman,
Completing your 10+2 is ideal for better prospects in terms of higher studies and careers. Doing a Diploma will limit you to a particular field only and you won't be eligible to take most entrance exams.

To become a doctor, one should have biology as a subject in class 11th and 12th and there is no need to opt maths as a subject as you have to choose two subjects out of three which includes maths, biology, Hindi or any other optional subject.
After completing your class 12th, you can do MBBS to become a doctor. There are many entrance exams like AIIMS, AIPMT, UP PMT, etc.

Hi,

Hi Raghu,
The answer will depend on the kind of job you want to do in future and your interests/aptitude. Also, note that every individual has different skills and aptitude. You have to know your interests and areas of excellence. Complete your 10+2, figure out the subjects you enjoy the most and feel confident in.

Hi Harsh,
You must now ideally complete your 10+2. Which stream you want to enrol into is a choice you have to make by knowing your interests and aptitude. Identify the subjects you enjoy the most. Take a psychometric test as well.

Dear,
Firstly, you need to understand all the aspects of commerce field in class 11th and 12th and strengthen the foundation in economics, accountancy and business studies.
After class 12th only, you need to start the preparation for the same.
All the best.

For this, +2 with non.medical is required. So, go for it after passing the class 10th. Focus more on PCM as this will be your base for B.Tech in astrophysics.
