my camp is coming up

yes, my camp is coming very soon... it is next week on Wed to Thur( my sec 3 camp) n i've only have Fri to rest before my CCA camp will start( Sat to Mon, NPCC camp).. i'm not sure wether i want to go to school on Fri or not... if i come, i would be too sleepy to consentrate on my studies n my body would be aching by then.... if i don't come i might get scolded for not coming to school n i would need MC; but i am not sick. how can i take MC from doctor, i can only provide a letter from my parents.... so i've decided that if i can make it, i would come to school because i don't want to leave out my studies. if i really can't make it, i wouldn't come to school n provide a letter from my parents. that is now settle... n if i never come that dae, i am sure me parents would approve n provide a letter for me........
