Thank you I understand,my middle name was mispelt that is why I asked if I can do it along side my regularisation

Hello everyone.
Please I need clarification on somethings.
We were told to do regularisation in a school for we that the school changed our courses. I recently graduated this year and my school is in ondo state but I'm currently in Lagos and I'm planning on doing it here in Lagos.
My first question is how much just regularisation now? Please I need current information...
My middle name was mispelt in my jamb instead of OLUWATOSIN it was spelt OLWUATOSIN. Is it possible to correct this along side my jamb regularisation?
And also I have mispelt names on my waec result,I have been to the waec office as at 2019/2020 and I paid 10,000naira for correction of name but I was told I can't correct mispelt but misplaced name.Please I hope it won't affect me for NysC cause I have affidavit for the mispelt names and that was what I used in school for registration.
My surname was supposed to be SANUSI but it was mispelt as SAMUEL IN WAEC,I had another waec sitting and my middle name was not complete instead of OLUWATOSIN it was just TOSIN.
NOTE: I used 2 sittings of waec result for school.
Please I am confused on what to do.
