Hello aspirant,

Yes, you can take admission in Science stream under NIOS Board, after passing from Maharashtra board based, on the marks you scored in class 10th . But you have to study from class 11th again if you wish to change your stream from Commerce to Science. So, you must study from class 11th once again in order to complete your class 12th from Science stream.
