JNTUH Results Release Information & College Re-open Info

Coming to the results of the exams conducted in the month of November ( 2-1 Regular, 3-1 Regular,4-1 Regular )  are going to be released mostly in the first week of January firstly 4th year results will be out followed by 3rd and 2nd year there will be one week gap between 4th year ,3rd year,2nd year results respectively . 

 

 As Previously we said colleges being reopened tomorrow i.e 7-12-2015 . Most of the students requested to increase holidays but JNTUH didn't even respond on that issue and  the academic calendar  which is updated previously is only confirmed for this academic year i.e supplementary exams will be conducted in the month of feb going into the details as most of the students requested to conduct supply exams with other schedule rather then conducting with regular exams , JNTUH officials had Agreed for it and given the academic calendar according to It.
