For self-directed studies my dudes, you must enjoy every second with your friends while you are studying. And if you are interested to take the ACT and TOEFL exam, use the books in the SASC, personally when I'm doing it I use to listen music. Moreover, do NOT forget about your evidence for the week it will rest you points that are important for a 100% if you always want perfect grades like me.
For Writing/Grammar you MUST stay awake in miss Healy class, her classes are not bored and is enjoyable if you pay attention and participate. For sure, that I like to stay awake until 1am I used to drink MOUNTAIN DEW, with caffeine, or Root Beer, because it is awful flavor it makes me feel awake, but if you can sleep early good for you. Stay in class early, do not forget to bring chew gum it help your mind stay awake.
Have a nice semester in GAP, and remember my fellows enjoy your time during Academic Preparation, the time goes fast that tomorrow you could be in the last week of class, like me.
