A thought! when i was in 120 minutes mark ,loadshedding happend and when i reopend again within a minute! all marked answers were lost!
thank GOD! i write down all answers while solving ,in copy and again just marked them in near about 12 minutes..from scratch..but after completion it is showing my time 133 min....means previous 120 is taken in account..ok..but then answers should also come marked while reopening.
periodic update to db will solve this
ps:my final year project was on an online exam system for entire college,and had to deal with this kinds of issues always!so don't mind for this extra suggestion
