rofl its my phone's autocorrect. (iPhone bleh)
Dude I still want like main errors possible with protactors and stuff cuz like all I know is we need to clamp it foe better results as it is in air or some sh*t. Help
ah yeah, out of all the past papers only one error/improvement thingie was about protractors. the one with the bottle and measuring the angle? it's similar to the one we had in may/june.
but yeah, it only said that you can use a clamp to hold the protractor still (you get no credit for saying "a clamp to hold the BOTTLE" though) because it's hard to keep it steady while holding the bottle as well.
other than that, i'm just as clueless as you are
