Class 11

Hi, Both are good courses. You not need to be good at Maths but you should be good at accounts because both courses deals with accounts. And according to me FRM is best. But you should choose only when you are comfortable with it.

After class 12th give entrance exam.
Competitive applicants tend to have a composite score of 100 or above with demonstrated consistency across the four sections of the exam (reading, listening, speaking, and writing).

PCB, Biology is for Medical courses.

No, if you take PCB stream then you will give only NEET.

Candidates must pass Class 12th from a recognised board. The minimum qualifying score accepted by most of the universities is 50 percent aggregate. However, some colleges might have no minimum score. Candidates must check the eligibility criteria set by a particular college before applying for admission. For UG-level admission, there is no preference for the stream studied in Class 12th. However, candidates who have a background in the field of social work, sociology, psychology, or any related field are preferred if they want to pursue a BSW course.

To give the 12th standard examination after a gap of 3 years after completing 11th Science, you can contact the board of education in your area and inquire about their procedures for appearing as a private candidate. In India, many state boards allow students to appear for their 12th standard exams as private candidates. You may be required to fill out an application form, provide proof of your previous education, and pay a fee to sit for the exams. It is advisable to check with the specific board for the exact requirements and procedures.

No, you cannot but you have to choose PCB as subject.

B.Com programme or B.Com Honors will be the best.
