Maximum permissible gap between CA INTER and CA FINAL

Hi..i completed my CA-PCC (inter) as well as articleship in 2014. I registered myself for CA FINAL but could not attemp any exam as i joined job as lecturer and had to discontinue my studies..so now after about 6-7 years of gap, can i give ca final exams again after re-registering myself for the same ? Or would i be required to start from the beginning?
