Exam

My exam week start last week, this week is my last exam for my Pm. Haiz... I quite sad and worried. It seems that something is bothering me to study..things that I could not focus on.. I been studying and do all my revision but I couldn't concentrate. My mind is blank..my heart is not here..

All the answer that I wrote, all also from my own thinking..my own opinion..and doesn't follow the notes that given. My heart now.. feeling worry...sad...scared..blind..What should I do? What I need to care?What I need to do? Why...
