Basically GSEB stands for Gujarat secondary education board and GSHSEB stands for Gujarat secondary and higher secondary education board.

GSEB conducts board exams for 10th standard students where as GSHSEB takes care of the examination held for higher secondary or 12th standard students.

So, Basically they are same but only conducts the Exam of different Levels.

But for any queries you have to contact the same place that is Sector 10-A, Gandhinagar.

hello aspirant ..

hope it helps !
