When filling out a government job attestation form, if your 10th-grade certificate shows a different school name than where you studied, you should list the school name as it appears on your official marksheet and certificate. It's advisable to consult with your actual school first, as they can help get the forms attested correctly. If that's not possible, you can use the name from your certificate and get it attested through your study school. This is generally a technicality and shouldn't affect your job eligibility.
