It is always averaged.

Because the parabola is a tangent at that point. A parabola can only ever be a tangent to the x axis if it has it's vertex at a point on the x axis. It can never touch it twice in that case because it's an increasing function only.

\text{a)} y' = 2x + b \text{Since it's tangent to the x axis at 5,0 it means the gradient of the parabola at 5,0 is 0 because the gradient of the x axis is 0} \therefore 0 = 2(5) + b \Rightarrow b = -10 \text{Figure out c easily by just subbing the point (5,0) in the original equation of the...

It’s Appa from ATLA! Come on it’s literally the best cartoon/tv show series to ever exist.

I want it to become safe enough so that gyms can open :(

Well my courses were Pass/Fail and I passed so I'm happy.

Haha what seriously formal on the oval??? Well hey it’s not much different to James Ruse which apparently does its formals in the school hall...

Haha its totally fine. Every year thousands and thousands of people use it including all of us here.

Sam D's textbook is The GOAT. It's what gets people the band 6's and I can vouch personally for this. I loved the Sam D textbook.

External is the final HSC Exam at the end of the year. It is a mark of how you performed on that exam. Internal is a culmination of the marks for your assessments and assignments you do in year 12 in your school. Together they make 50% each of your FINAL mark. Their average is taken to calculate...

No see this is a major misconception. Lets talk about 2U Maths as an example. If you went to a school ranked 500+ and achieved straight 90s, ranked 2nd which was equivalent to a straight band 6 for that school, and then you went to James Ruse. At JR you would be ranked probably in the 50s...

Because most high school students get caught in the hype of 'better school = better ATAR' not realizing that it's nothing but your hard work that gets you a good mark. I went to a school that was ranked 300+ and I did just fine.

I wouldn't say this. It is highly inaccurate because school does not directly affect your mark or scaling or whatever else. There have been many discussions about this here on bos and so all I'm gonna say is do not worry about it. No it will not directly affect scaling or your marks, just focus...

This! I memorised straight from the textbook for my most content heavy subject and it got me a high band 6! Everyone studies differently as mentioned above.

Above anything you should do high levels of Maths, at least Extension 1 because looking at the degree it assumes your at least at that level. As for business and eco, I'll leave that to people that actually know the answer to that.

You'd be surprised of the effectiveness of writing your goals down. Write down everyday what you want accomplished and tick it off when you do it. This gives you a sense of accomplishment and also makes the large task of getting a good mark seem doable because your setting goals everyday which...

I did the exact same thing as you and it worked out well for me. Everyone is different imo. Writing notes is not something that has ever really helped me and I've basically never done it. I study much better by spending most of my time doing problems and memorizing content straight from a...

Done.

Most people say they are equal. The scaling is also basically equal, although I think with the New syllabus Physics may be considered a bit harder by some people. Does it really matter though? Why be so concerned over a subjects difficulty. If you like it go for it! Personally imo HSC Physics...

Also may I just add, it's always possible to drop business studies in year 12 but you can not pick it up, so the safer option is to take twelve units and then if you find out your doing really well in your other subjects and business studies takes up too much time then you can drop it. It's up...
