Hahaha... exam stress... (I have my last AP tomorrow so my stress is winding down~!! w00t!!)
What I generally do is turn on music that I absolutely HATE, and then tell myself I can't turn off the music until I finish a certain portion of whatever it is I need to study for. This also makes me more efficent, because I study quicker in an effort to turn off the music sooner ^o^ However... I think this doesn't work for most people, because out of all my friends only 1 agrees with me that this works... ^^;
wel my exam is tomoro, and i have followed all ur advice. everyday since i posted this thread, i studied 2 hours, and took 15 minute breaks every hour, and did one hour session with my friend. so i hope i pass tomoro so THX!
