Yes, you have high chances.

You have high chances of being getting selected.

You have to be strong in biology as well as in chemistry and after 10th you must prepare for PMT.

Dear Raj,
Please check the admission criteria on IIM B site. It says, the candidates percentage scores in
the 10th and 12th board exams are initially adjusted by dividing each such score by the 90th
percentile score obtained in that board. The database of 10th and 12th scores of all CAT
applicants of the past two years is used for identifying the 90th percentile score for each 10th and
12th board for this purpose.
However, I am not sure how it works for OBC category. You can contact the admissions office to understand you are eligible or not.

Obviously not 10 years. But you may write 1 year as you have completed in 1 year.
