Hello Vikas,
At the time of form filling itself, you must twice check the form before its actual submission. PUC number is the most important parameter in CET exam which later has its influence on post exam counseling. You must now wait till the correction window that begins shortly after submission of CET forms and remains open for 1-2 days. You may also try to mail the CET Officials about the same consent. Last option for you might be to wait until beginning of counseling rounds since your profile is unlocked for editing before entering counselling rounds. Till that time you check the CET portal from time to time for editing window.
Hope, this answers your question...
