Hello Aspirant,
Yes you can do so. Some ways through which you can improve your marks is either appear for improvement examination conducted by the respective board from which you appeared last time or you can appear for NIOS or any other recognized open board and they provide the facility for On Demand Examinations and for the same you can appear PCB combination in which you want improvement.
I hope this information helps you.
Good Luck!!
