Osmania University — examination schedule

Sir,
This 4th sem examination schedule was so much of burden for the backlog students. Continues exams for backlog students even some day there are 2 exams, so just imagine how much burden will be on that student.
With this system very less students can clear there backlogs in my class more than 80% students have backlog is problem is not only in my college even other colleges have more backlogs students than passing students. The students like me how's center is far from his house have to move 2-3 hrs before for exams so there is no time for nxt exams
1) backlog exams should be 1 month or at least 1-2 weeks before the regular exams nd some gaps should be there in between the exams
2) paper correction system should be improved
