Test!!!Test!!!

Yesterday morning i had my second EM test. But i did not really study for the test.So i planned to sleep early and wake up early to at least a bit. But!!!!! that Mr. Samuel does not want me to sleep early. From 12.47am onwards, i cannot even had my sweet dream. 12.47am message me, 2 sth message again and followed by 6am message me again. That's not the only thing, starting from 6.31am onwards, he missed call me up to 6 times. Luckily did not really affected my test or else i really going to kill him. Samuel, Wan Shin and i had studied together early in the morning around 7.30am and having test at 10.30am. There's some photo below:
