Hello Aspirants,

Hope you doing well, As there is not much difference you will get but yeah CBSE board is considered as more focused on the side of Science and maths and State boards are more focused on the side of regional language, local topics& state-level matters and yeah CBSE is considered a lil bit easier the state boards but as you have told that you have done your 11th and 12th from CBSE  so you have already a knowledge of your recent subjects so i dont think that for you the state board will be tougher so you are good to go with the state board
