hist ext you can pretty much do in a few weeks if you go hard out. but you just need to make it look like youve done it over a long period of time. here is mine if you want to have a look http://science-warfare.blogspot.com.au/
i was kind of the same about 3 weeks ago, but i have just been practising those and now im getting close to full marks in the q10's. so just keep practising, you will figure out that most of them are just confusing algebra rather than hard concepts.
but then again there are always going to be...
should have done 3u maths and potentially 4u (if i was to do well). add in chem, and maybe drop modern(even though i love the content) in year 12 so i can keep hist ext. if that is possible.
because LHS said i should.
school rank ~130 last year but fluctuates.
adv english: 2-5/25
mathematics: 2/30
physics: 1/20
modern:1-2/20
History ext: 1/4
sor1u:2/50
need ~95 for adv sci/eng
from what ive heard the main downpoints are costs and distraction from uni work. but i guess if you can manage those, then it would be fine. im going to try it for a year next year too, hopefully.
i was taught that those experiments were like the first evidence that pointed towards particle nature. i wrote this in trials and i got full marks for the question, so im going with what i know.
qualities of wave:
- diffract
- reflect
- refract
qualities of particle
- thomsons charge to mass ratio experiment showed light was of charged particle nature as mag + elec field deflected/attracted the light
- the paddle wheel experiment
- photoelectric effect
light has dual nature of wave...
physics is 80% theory and 20% mathematics in HSC... according to my teacher. but HSC physics only really has equation substitutions and easy stuff like that.
