My feeling on that lessons is....

On last friday, i feel quite fresh..... although i didn't sleep the last night..
but after half an hour, i feel quite sleepy because the subject that teach by Ms Crystal had been taught bebore last year... the other reasons is also i didn't have enough sleep....
Most of the lessons that been taught last week, i understand the topics, because i have learn it before..
the maths ex i have't done because this few days i'm relax and do nothing..
but i have to do more ex to improve my maths also because i'll forgot it if i did't done the ex..
