Will the real TeeEm please stand up!

they all work the same
I made 4 questions yesterday, some are harder.

expand
look for patterns to cancel
get a compact simplified answer
let it run to infinity

I see. Spotting the pattern is where i'm struggling (this trend follows for the majority of your questions, it's the spotting of the pattern which is my downfall). I got very frustrated trying to 'spot' the pattern earlier today. Annoying because it isn't necessarily hard and its not a case of learning a new technique, it seems you either see it or you don't. I can only hope that with experience I will become better at 'spotting the pattern'.

the reason you cannot see is how I wrote it
look at yesterday's question.
if you generate terms as it is you will not see it.
when rewritten in factorized form and generate terms it is not that hard to see.

same with today
you need to rewrite it nicer and then generate terms

these require algebraic/mathematical maturity... no knowledge

That is the Q that really annoyed me. I changed it before generating terms. But changed it to a single fraction. Not two fractions like you did. I never thought to split up the fraction how you did. Which is obviously why i didnt spot the pattern.

I will try again with today's one....




That's what I meant, and this is why it frustrates me...in normal A Level if you don't get the Q it will be down to a gap in knowledge which you can rectify on the spot. This is different. At last that is how I see it.

I wish somebody would tell me how these questions compare to AEA and STEP.
my intention is to be slightly easier (most of the time)

Both the normals and the Extras or just the Extras? I believe physicsmaths took STEP...

the normals are hard
the extras are even harder
these are not standard exam questions
gome44 is very good but he did not take STEP

I need to remember that when I get frustrated over them....
Are these questions examples of the style of questions you will be making in the future? I know you've mentioned in the past about making questions for the very top end.

I am making these questions for my SPECIAL papers which I am about to start writing as soon as my holiday is over

How quickly will you be making them? I think I will find them very useful.

please be sure to let me know when the first goes live....i'd be interest to see how 20Qs in 3Hrs would feel.

I will make an announcement but I will not post those here.

I do not blame you

I checked them today the best I could, but when you mass produce like I do, typos/mistakes are inevitable ...

At the very start of the solution to Q24 (normal, not the EXTRA) you flipped the sign to a negative. Surely the denominator of the fraction needs to change to $2^n-2$ or am I being stupid?

maybe you are right
I will check

isn't what I did?
