If you are trying to fill the form for Class 11 and are not able to complete it, the first step is to check whether the school or board has officially opened the application window. Sometimes the website becomes busy or forms are temporarily unavailable due to server issues. Try reopening the site after clearing browser history or using a different device or internet connection. Also make sure that you have all the required documents ready in the correct format such as passport-size photo, previous class marksheet, Aadhaar details, and parent details, because missing information can stop the form from submitting. If the problem continues, it is best to contact the school admission office or helpline so they can guide you directly and also check if there is any error from their side. Many schools also accept offline forms when technical issues arise, so you can ask about that option too. Hope this helps, and all the best.
