When you say you are pretty all rounded, does it mean you are rotund?

It looks like you are unable to "get it" by yourself. So you will need someone to help you, if you can be helped at all. Going to a Chemistry coaching centre isn't the place for you. You will need someone, like jazz519, to give you personalised help. Getting a "right person" to help you is very...

One suggestion: In the end-of-school-term Lifeline book sales, you can often pick up a good uni 1st year American Calculus text book - usually for less than $10. (I once picked up an unused hardcover university text with about 1000 pages: Physics - by Young & Freedman for only $2!). This...

Sorry - didn't read your full post!

Use fact: coeff of term in x^n of LHS = coeff of term in x^n of RHS and note fact that nCr = nCn-r.

If so: xlny\frac{dy}{dx} = 3x^2y \\ \\ \therefore lny \frac{dy}{dx} = 3xy \\ \\\frac{lny}{y}dy = 3xdx \\ \\ \therefore \int \frac{lny}{y} dy = \int 3xdx \\ \\ \frac{1}{2} (lny)^2 = \frac{3x^2}{2} + \frac{C}{2}\\ \\ (lny)^2 = 3x^2 + C \\ \\ lny = \pm\sqrt{3x^2+C}\\ \\ \therefore y = e^{\pm...

Why are you doing Physics if you don't even like maths? You will be handicapped in your Physics, even if it has been mathematically diluted.

Tiring, but maybe in the long run, helpful.

Cujo10 has little choice, unless, somehow miraculously he can learn to write. I've tried to help quite a few individuals over the years with their handwriting but unfortunately the results are not very good.

Inability to write & poor handwriting is unfortunately a modern day phenomenon. Ages ago, hardly anyone had handwriting problems. Our teachers were not as "well-qualified" as today's teachers - our primary school teachers had no degrees. From my observation, once you have learnt it incorrectly...

Stage 3 is low level maths. Did she mean 5.3?? Also agree she should take it up with teacher that she wants Advanced Maths. The teacher may have assumed, from her past performance, that she'd be more comfortable with "Standard". Akuri - get yourself switched to Advanced quickly, while it is...

R_n = S_{2n} - S_n\\ \\S_n = \frac{a(r^n - 1)}{r-1} $ and $ S_{2n} = \frac {a(r^{2n} - 1)}{r-1} = \frac {a(r^n - 1)(r^n + 1)}{r-1} = S_n(r^n + 1)\\ \\ \therefore \frac {R_n}{S_n} = \frac {S_n\times (r^n + 1) - S_n}{S_n} = (r^n + 1) - 1 = r^n\\ \\ \\ \frac {R_8}{S_8} = r^8 = \frac {1}{81} =...

I've tried to re-learn Chemistry (using Chemistry for the IB Diploma SL, Derry et al) and it's so different from when I first learnt it. I've read: 1) Atomic Structure, 2) Bonding and 3) Periodicity. About to embark on: 4) Quantitative Chemistry(Avogadro's const, mole, relative atomic mass...

Also, hqblues, with tutoring in 3 subjects, where are you going to find time to do your own studies? Just curious. I remember a student of mine, apart from tutoring in maths, also went for tutoring in Physics, English and maybe another subject. It's so overwhelming work load! Remember, one...

Dr Du's maybe good at Maths tutoring, but are his Chem & Physics necessarily as good? Unless he is an expert in these himself, he'll have to depend on hired expertise to deliver those courses. If he gets good teachers, the offering should be good, and vice versa.

Wow! You have to be good enough to be a student of Dr Du's. But that is understandable. By weeding out sub-standard students, he's able to ensure a better outcome for his coaching centre. Also homogeneous cohorts are easier to teach. Also the school gains further reputation of being an elite...

I get annoyed when I read things like "Asian education systems are notorious for their rote learning . . .". 1) 1st Asia is a huge continent. Although Indians strangely enough are not considered Asians here, of course they all are. Afghans are very different from Burmese, who in turn are...

"your"?? "you are" or "you're"!

With 5 students completing their IB last year, I'm now looking forward to guiding a few more this year.
