3th class - math formula !@#$%

oh noe... i have never seen one of those for a long long time. The two formulas are like the one in phy and I HATE PHY so much back in high school.

when class ended
*called my friend and ask him will those 2 math problems on the exam. He said no need to worry, they won' be on the exam. I'm so glad !

after that went to mcdonald and ordered a yummy meal.

i don't eat fries nor the drinks from mcdonald anymore, so i change to salad and hot chocolate

The 宵夜 was AWESOME !
