Qualification for swimming lesson?

Today, Sports & Wellness teacher hold a swimming test to see that weather or not do you still need to attend the swimming lesson for 10 weeks. Well i PASSED! But this time, i don't think i did quite well cause i did not eat breakfast in the morning so no energy to swim. I LOST my survival sliver certificate, can't find it anywhere. sobs! After Business Fundamentals, my friends and i seems to look like hungry ghost lols. Too hungry, feel so weak.
*(Tips: Eat breakfast everyday, that's very important mission to do daily! XD)
