CA Final registration revalidation

i completed my 12th as private student. is this ok if i submit 10th school leaving certificate?

Would you be able to tell me what is required to be filled in date of registration in online revalidation form as i have filled my initial date of registration i.e when i first applied for final registration(in 2012) but not the current date.

i called at icai office. they confirmed date of re validation and it was same date when i applied for re validation. they told that it will take time to issue letter but you can apply for exams. 

thanks

@ Deepmala i had a query.. i filled revalidation form but cudnt send acknowledgement to regional office... can i apply for the exam now... before the processing of revalidation form.. coz even if i send it by speed post it would reach in 2 days and then processing would take time.. by then the time will lapsed for exam form.. what to do...
