Results for the IDT mid term checkup

I scored 73% which is not bad considering the fact that I only look through the material 3 hrs before the actual test. However, I just wonder because it took me only 3 days to know the names of 70 students (32 in P2 and 38 in P4) including where they sit but having been a believer for so many years, I still recall certain verses wrongly. Maybe I ought to put on sackcloth, go fast and pray.
