I agree with sab13562’s suggestions. Exercise is very good for the circulation - it promotes peripheral vasodilation and you’re likely to feel more mentally alert, noting that you are studying for your HSC exams this year.

It is also the tune for the alphabet song. 😀

Apart from the parabola, all the other conic sections (circles, ellipse, hyperbolas) have two y values for each x, so by definition, their Cartesian equations aren’t functions, whereas the dual parametric equations (for each single Cartesian equation) are functions.

Butter & salt on popcorn is classic and my kids and their friends love it and haven’t really been interested in anything new, however, some interesting flavoured salts you could try are chicken salt and truffle salt. We use these to jazz up other foods, although our kids just prefer classic...

The concept of a Cartesian plane incorporates the notion of an independent variable x and a dependent variable y that is a function of x, but, as per extremelyboreduser’s example of projectile motion, there may be a relationship between x and y, but they are dependent on other variable(s) rather...

Remdesivir is a RNA polymerase inhibitor, so it is primarily an antiviral agent, however, after many decades of the conventional wisdom being that antibacterials are of no benefit in treating viral infections, due to slow progress of developing effective viricidal agents, many clinical...

If you are not accelerated, depending on your school, if you take Maths Extn 2, you may end up studying Maths advanced (2 unit), Maths Extn 1 and Maths Extn 2 all concurrently in Yr 12. My eldest did that in 2015 - it’s possible but quite a challenge because maths is foundational so it’s better...

Honestly, I’ve always found the phrase ‘leadership skills’ to be little more than a catch cry. On the other hand, I try to pick up useful skills and would call myself a ‘Jill of many trades’. I have always said to my colleagues and seniors that Chiefs need Indians and asked what the world would...

Yes, from the email broadcasts that I’ve been getting, that seems to be the general advice again.

I’ve looked up the ANU website regarding their student residences, but would love more information from anyone with direct experience. Many of them list having ‘music facilities’, but how much access would a student have to either a piano or keyboard? Do any of the residential colleges have...

I’m very sorry you had to live through that.

I think physical distancing, masks, hand & personal hygiene are very important and large crowded events should be avoided, but I was dismayed when they restricted apartment dwellers in ‘LGAs of concern’ to one hour outdoors per day (we live in a semi rural area so it didn’t apply to us) because...

You can use Pythagoras‘ theorem to help remember the angles and ratios of the sides of these two very special triangles (1. half of the unit square and 2. half of an equilateral triangle) - then you won’t need a calculator to work out that cos 30° = √3/2 and therefore that 60 cos 30° = 60 x √3/2...

I’ve been thinking there needs to be something other than an immediate knockout round given that white usually has the advantage over black in choosing the opening.

I think you made my point.

I’m appreciating our local high school more & more. They offer triple science (Bio, Chem & Phys). In fact, the Science dept would probably accommodate Earth & Environmental Science to be studied as a fourth science subject if anyone were keen to do it.

I’m neither encouraging or discouraging students to study for a Bachelor of Medical Science degree but to set the record straight, it’s not a dead end with no prospects. A graduate with such a degree would meet the minimum eligibility criteria for positions of clinical scientist (with potential...

Your choices are very relevant to medicine and most of these subjects would probably scale well (I don't know much about PDHPE but you do have twelve units). Are your two units of English standard or advanced? Definitely recommend advanced WRT your stated goals. BTW, scaling of each subject is...

My eldest did 4U Maths, Eng Adv, Chem, Eco, Bio and Physics. The idea was to drop one subject if she was weak at or didn’t like it, but she couldn’t decide which one to drop, so she continued with all 14 units. It probably cost her slightly in terms of her ATAR as she spread her efforts more...

Hi OP, I’m a mum, so I’ve had time to reflect on this issue. Unfortunately, some mothers, like mine, will never be happy no matter how well their offspring do(es). They are probably trying to live their lives through their children, but it’s YOUR life. In addition to Katsumi’s great advice, be...
