Stress

Exam is coming. Time flies. This sem's gonna end soon. Before my mid sem exam, I think I can cope and understand what the lecturer has taught. But now... What a contrast! Things are getting tougher and tougher suddenly. I don't really understand what I have learnt. I don't know what's happening about what I have studied. Oh no! Have to seek help from God! Oh God please be my teacher, help me to understand what I have learnt... T-T
