lol disadvantage of AAS is that its also time consuming as you have to use a different lamp for each sample and obtain a calibration curve every time before testing
untrue. the line of best fit is advantageous as it gives different weighting to different data depending on deviation from the trend. this minimises the error produced and thus there is not always the same number above as below
if you know your preliminary well it assists you in developing fundamentals throughout hsc which most people tend to forget as they learn the course superficially
throughout the course the majority of the formulas will be explained in their derivation (the jacaranda textbook focuses particularly on this). some of the formulas are just assumed like law of universal gravitation.
also most formulas given are very fundamental and are used to derive more...
shouldnt your line of best fit intersect the origin for things such as plotting a pendulum experiment? otherwise you assume that your experiment is already invalid?
not necessarily harder but probably more creative. lets be honest how hard do the papers really get? its just about nailing specifics and not making careless errors
personally i think its not too bad; it just depends how you work through the stuff they give you. theres heaps of questions and you can read the worked solutions. i think it greatly improved my section 3 score but not as much the others. i managed to get 93 percentile which is decent but not...
