do i need to upload my caste certificate while filling APRCET application form? i applied for BCB caste certificate ,but it takes about 10 days to get it .can I apply now and show caste certificate when I selected ?

You do need to upload your caste certificate while filling the APRCET application form if you belong to SC/ST/BC categories, as it is mandatory for category-based reservations and fee concessions. However, if your BC caste certificate is still pending (takes about 10 days), you can apply now by mentioning the certificate application number or provisional details if allowed, and submit the actual caste certificate later when available, typically at the document verification stage after the entrance exam or selection. Make sure to keep the official receipts or proof of application to avoid any issues.
