Just reading the 2016 UAC Scaling report, the maximum ATAR achieved by a student doing English standard was 99.70 Legal Studies, Modern History, and Economics was 99.95 General Maths was 99.6 General Maths scales poorly and Standard English is hard to get high marks in (99.9% of students got a...

Tbh, bio felt similar to every other year in recent times. Got around 17-20 for previous years in MC, think I got 18 this year. Short answer was the same as every year, typical straight from syllabus questions except for the typical 7/8 marker at the end of core which I thought was probably...

I think I lost 3 in bio and maybe another like 2-4 marks depending on how strict the marking for short answers are. Do you think a 93-95 raw has a chance to state rank biology (1st internal as well)?

Hey Jazz with that question there was a scale on the diagram of like 2cm to 1000km. Do you think we needed to use that at all? (One about metal smelter and coal fired power station)

I believe Question 8 was along the lines of "Which of the following could be added to a solution to determine the presence of Ba^2+. The solution also contains Pb^2+ ions?" something like that, and for each of the 4 options you were adding the sodium salt. Question 9 showed a spirit burner with...

lol nvm

Based on the answers you've provided one of q7-9 was a question that asked something along the lines of "What is the density of ozone at 25degC, 100kPa?" Answer - divide molar mass of ozone by molar volume (at RTP) and you get 48/24.79gL^-1 which is 1.936... option C

I agree with you and the solution, the force on the magnet is down so there's an additional force of BIl on top of the weight force and yea we divide by 9.8 for mass

Ok, so we're given an initial velocity of 10ms^-1 and an angle of 60 to the horizontal So initial horizontal component of velocity is 5ms^-1 (ie 10cos60) and initial vertical is 10sin60 (around 8.66) At max height, vertical velocity is 0, so 0 = 10sin60 - 9.8t t = 10sin60/9.8 This is half the...

I got from memory around 9m

Anyone else think aligning will be better than previous years? MC was definitely harder and core had some pretty weird ones like the blackbody curve.

Yea area under Flux/time curve isn't magnetic field strength pretty sure we're correct.

Magnetic field strength is flux per unit area. The maximum flux on the flux vs time graph was 0.6Wb I think so the maximum magnetic field strength over the 12 seconds would be 0.6/Area of the loop. Then for part b), the rate of change of flux (flux vs time) is the gradient of the curve which is...

That's what I did. If you didn't assume it was a circle, how would you calculate area?

Oh well It's over, BUT I asked my tutor this after my trials (she's a HSC marker) because I didn't write a conclusion for one of my essays. She said that in the HSC most of the time you are not deducted marks for anything unless you write things that are straight up wrong/contradicts your...

I'm not gonna give a definitive answer because I really don't want to overestimate your ATAR and raise your hopes, but I'd say 99.5 is probably within reach especially if you do well in externals. You should ask your principal/careers advisor or whoever gives ATAR estimates at your school...

99.50ish

IMO if the only reason you would want to continue doing physics is Medical Physics, I'd suggest against it. Our school does the medical physics option and there's really little relevance to anything in medicine. It's mainly just learning about diagnostic techniques and an outline of the physics...

This question is from the Cambridge year 12 extension 1 book Exercise 3G - Projectile Motion - The time equations question 17 part b)ii) I've done the other parts of the question just not sure how to go about b)ii). I tried double angle results, not sure if I've made a mistake somewhere...

Yeah, I'll definitely be able to finish the section 3 and maybe even the section 2 drills. I don't really plan on finishing the section 1 drills, they haven't really helped me much. The problem solving questions can have tricks to them sometimes but I think its more up to me to see them on the...
