Physics

National Institute of Open Schooling (NIOS) is the best option for you. NIOS conducts On Demand Examination (ODE) that NIOS Student can walk into the examination center as and when he/she feel ready for the examination. This allows the Student to get assessed when he/ she is ready. Readiness depends on the Student and not on the institution. The degree and level of performance is decided by the Student who can reappear in the examination as many times as one wants, till satisfied. Further you have to take the fresh admission in 11th in M. P. Board's schools if wants to repeat the whole 12th. This seems not justifiable because you have already passed Physics and Chemistry in year 2000. So NIOS ODE is the best for Biology.
