Oh, I see. Thanks a lot for your reply.

The website (Faculty of Medicine - FAQ_local) says that if I have a predicted UAI of 99, I needed to get 58 in UMAT to obtain an interview in the past three years. However, I have also heard from somewhere else that I need at least about 90 UMAT score to get an interview for medicine. Which...

Hint:f=\frac{v}{\lambda } $ and E=hf and see if $E\geq\phi$ or $E<\phi

No of premises with a window lock but without an alarm=237 No of premises without an alarm and a window lock=1923 P(No window lock out of the ones without an alarm)=(1923)/(237+1923) I hope I didn't make any calculation error...

Use a Venn Diagram.

Metals such as Mg have a different bonding structure to that of molecules. Read the 'sea of electrons' stuff from prelim chem textbook. They are not molecules.

Your definition of molecules are incorrect. A molecule is the smallest unit of substances that may exist by itself in nature. Noble gases are both atoms and molecules by themselves without covalently bonding with other atoms.

well, no time to post working out but p=0 when you expand it.

Hmm... Maths is surely more logical and practical, but English is also pretty logical when it comes to AoS responses.

coz they can't bullshit...

degree of depth+cohesion

Region bounded by y=x+x^2, x=-1, x=3-x^2 I.e. y=x(1+x), y=3-x^2, x=-1 The following info may easily be deduced. y=x(1+x) has two roots (0,0) and (-1,0) and is a concave up parabola y=3-x^2 is concave down parabola with y-intercept 3. x=-1 is obviously a vertical line. Now if you have...

no worries

well, this question required too much simple algebra (simple, but easy to make mistakes) I made those mistakes more than once in my 4u half yearlies lol...

$Somehow I'm not getting 1... Tell me what I'm doing wrong... \\V=\pi\int_{-1}^{1}(R^2-r^2)dx \\=\pi\int_{-1}^{1}((3-x-x^2)^2-(3-3+x^2)^2)dx \\=\pi\int_{-1}^{1}(((3-x)-x^2)^2-(x^4)dx \\=\pi\int_{-1}^{1}((3-x)^2+x^4-2x^2(3-x))-x^4)dx \\=\pi\int_{-1}^{1}((9-6x+x^2-2x^2(3-x))dx...

insufficient information unless you mean 5^2x-5^x-20=0 and I guess you actually mean 5^(2x)-5^x-20=0?

Then my aim is 97~98+

I'll only comment about the ones that have not already been discussed in this thread. Maths Extension 1: Good ESL: crap unless you get band 6 Indonesian Background Speakers: All background speakers scale badly. Physics: Good

Generally, for aligned mark of 95+, what raw mark will at least be required?
