YES EXACTLY. I'm just bad at explaining it.

lol...You can take it as both inwards or outwards. But when you're solving forces you take it as outwards. If you want to take it as inwards you have to equate it to -mrw^2. I really don't know how to explain this over the internet. But the forces are equal therefor outwards=-inwards. Cmon...

No matter how much prems/combs you practice, the bos always finds a way to give us a fucked up question with a fucked up explanation that only like 2% of kids will get. lols I hope there isn't too much circular motion. :(

When you draw the triangles of forces. You have to give them directions. mg is ALWAYS Downwards. MRW^2 is ALWAYS outwards meaning the opposite direction as the particle. Then you just resolve forces meaning solve for horizontal and vertical. I'm sorry but you really should know this as it is...

Past papers, past papers followed by more past papers.

Hey! I might be doing bachelor of Advanced science at USYD next year. I just wanted to see how you are finding it and what your GPA is if you don't mind? I am planning to transfer into med. PS is it easy to maintain a 6+ GPA?

yeah.. let's just discuss it here. Since most people do communication anyway.

Re: HSC 2013 4U Marathon ahhh yeah... i never even thought of drawing the triangle. Thanks a lot.

Does anyone do the communication option? Can we discuss questions of this option as i personally find some of them way harder than the core questions.

Re: HSC 2013 4U Marathon Would someone please do question 9? I really struggle to understand it and have no idea as to how to approach it. EDIT: Sorry, i don't know how to use the maths tool on this forum so i just screenshoted the questions.

I thought that question was relatively easy in comparison to other years to be honest. Or maybe i was just strong enough in that area to do the questions because i got like 8-9/15 for q8 2010 and i usually get around 5-6 on the last question.

It is averaged and it's not too late to complain, although your school will not most likely change anything.

lol.. I'm aiming for 70%-75% raw. 4u is well and truly my weakest subject. Completely relying on the scaling to pull me up hahahha :D

re: HSC Chemistry Marathon Archive Wouldn't call it a 'spectacular waste of time'. Most answers include dot points meaning you can expand on them if it's a 7 marker. Plus. It's still fairly good revision.

lol. i'm exactly the opposite as you. I would jump in joy if it's lawn fertilizer or comparison of cells. I wouldn't mind it being AAS or oxides. but yea. I reckon this year it's going to be haber process.

lol, yes meaning?

Why would you even ask this question at this point in time? All you should be focusing on now is smashing your assessments.. Worrying about your atar comes MUCH MUCH later.

I can tutor you in 2u and 3u for $40 ph. I am completely familiar with the syllabus and know all the topics extremely well. I am available after November 4th.
