Is there anyway to know the CBSE 12th board roll number range for a school?
I assume you need roll no. range to download the all school result.Now, to get the result of any individual person, you basically need three things :- Roll No., School code and centre code. The centre code and school code are same for all the students of that school(generally).Here are the steps to get the roll no range :-You can try asking any of the students/friends ( from the same school which you want to get the roll no range of) for his roll no, centre code and school code.Then go to http://cbseresults.nic.in and start checking the results by incrementing the roll no(to find the upper limit of rollno) by 100 and check if the result is showing. After say some 2–3 increments when it shows error, assume upper limit of roll no is near to that value. Then start incrementing/decrementing by 50/20/15/10/5 to ultimately find the last roll no upto which the result is shown. This last roll no is the upper limit of the roll no.Similarly, start decrementing(to find lower limit of the roll no.) the roll no of the student of that school by same process and find the last rollno upto which result is shown. This last roll no is the lower limit of the roll no.Now you have the range of roll no. Go to the all school resuls page , put in the roll no range and your e-mail ID and Voila! You have all school result of that school.P.S. - Some people were asking if this really works. Here is the proof :-Hope it Helps!
