It all well and good to give advice but what's the reason for not doing eng/comm? You can't just say something without backing it up with some sort of logical thought.
Enjoy it obviously. I don't know what school you're from so I can't say how hard you'll have to work for 98+ ATAR but work just enough and then enjoy the rest. Study hard play hard. Don't burn out, don't overstress too much year 12 isn't that much harder. Take photo's throughout the year, trust...
If you need an explanation the four liquids are Ethanol(BP 78.1)/Water(BP 100)/Ethyl Butanoate(BP 121.0)/Butanoic acid(BP 163.5).
And distillation will obviously start from a water temperature of around 20 C upwards. The ester has the 3rd highest BP therefore the answer is C.
Yea it's possible to get over 95. I'm not sure how likely it is though. It'll be hard because your internal marks for everything except engadv will probably be below 90. But it should still be possible for 95+. Try the talent100 atar calculator and play round with the marks. You will get a...
You could literally get 99.9 since you're topping 8 units and second in adv english. So it's hard to predict accurately your ATAR. But 87 is defs possible.
Terry Lee is good for everything except mechanics. Patel is alright at everything except polynomials. I never liked Cambridge 4U, it lags behind its 3 and 2unit contemporaries. Getting those three should be fine. If you can only get two, Patel and TL if only one I'd recommend TL. In the end past...
There are about 250 school days (a little bit more). So you can miss about 40 days and still be within the 15% limit. Although I'm not even sure how much this policy/rule is even policed.
Nobody will know except for your teachers based on past years performance. Also if your marks are that high why not try 4unit maths, you can always drop down back to 3unit if its too much work.
