I have an exam tomorro afternoon, i only went to one lecture on this module, i have no idea what to do! im a shit student, if i get a degree there is something wrong with the system.
im supposed to be revising last minute but im cruising SG as usual, can anyone teach me the principles of of human evolution and early prehistory- all the various hominoids coming out of africa etc?? i have no clue, i didnt mean to take this module- christ i only usually go as far back as early neo, mesolithic if i need to but africa/asia and the whole paleolithic is fucking beyond me, i cant even blag this shit, i dont even know if its open book, essay questions or what? im gonna stay up all night an revise, but i dont even know wht i should be learining! im fucked!!! i hate exams, i get real nervous, always almost walk out, my friends have to drag me in to the room, an it gets worse, none of my mates took this stupid class! i dont know where the exam is, oh my god im so fucked, im officially paniking!!!
*calm down* deep breaths, it will all work out ok... right???
