Maths Extension 1 Predictions/Thoughts (4 Viewers)

Y'all, just confirming, for binomial distribution questions, is it fine if you use either sample proportioning method or the count method to solve the q's, particularly to obtain z-scores?
Thanks

They both work out to give the same z score, but if the question is clearly a sample proportion (says something like 'A random sample of 50 boxes from the 200 were tested' or something like that), then use the sample proportion method just in case.

Good luck today guys

Last year 9 marks were allocated to inverse functions so probably little on this today. I’m expecting a difficult polynomials question, lots of mechanics and maybe a difficult binomial proof in Q 14. Also they have never asked a plane or object suspended from a ceiling in ext 1 although it’s in the syllabus. They didn’t ask this in extension 2 this year or last year so may be something for today.

feel like there will still be a bit of inverse tbh

What difficulty would you guys reckon its gonna be at- 24 or 23?

I reckon it might be a lil harder than 24, also I think there will be an interesting vector proof in tis exam! Btw what time does the exam start?

Reading time starts 1.50 pm. Exam 2pm

@Allan Mekisic Do you have any final tips for us mate e.g. exam strategies etc? Really appreciated.

I start with question 11 which is usually easy. I leave the MCQs until last. Q 8, 9 and 10 are usually difficult and time wasting. You don’t want to be stressed 15 minutes into the exam.

Interesting strategy, I did something kinda different.
Basically, during reading time I started with reading the short/long answer questions and once I had finished those I started reading the multiple choice, answering them as I go.

Hmmm i might do 11-13 then MC and then attempt 14

good luck everyone! youll be free from maths after today and trust its the second most freeing feeling after finishing english

Yeah I think doing MC first was my downfall in ext 2

nahh i like math
