sir , BCECE ke registration details mai ,Gender aur category change ho gaya h ,Kay kare
But agar avi sb process baaki hai to kuch time wait kro.. uske baad login kr k dekhna,, shayad khud se correct ho jae.
If you have submitted your detail then it is very difficult to modify it. Details once submitted can't be modified. You should contact their helpline number. Give them all detail and request them to modify it. If they do it then well and good.
Hope for best.
Good Luck.
