Higher applications of maths

I am self studying the higher applications from the leckie and leckie textbook.
I have already found some (serious) errors which caused much temporary confusion.
Is there anywhere to get up to date answers? I was speaking to a teacher the other day and she commented how bad the answers are, that she's written to Collins to state there are errors but has never heard back.
I'm currently working on an expected value section and after trying a variety of things due to a slightly ambiguous question I Cannot get one of the answers at all and think it's a mistake in the book. Due to the length of question I'm aware I Could have a mistake in my working too (hence checking the answer) but any errors I do have would take me further from the answer not closer!

If anyone is interested In trying it:
You pay £5 to pick a card from a shuffled deck, if you get a queen you win £10 and you get to draw another card. If you get a 2nd queen, you get £100 or conclude the game by not getting a queen. If you get a queen you draw a 3rd card, queen =£1000 plus another draw, no queen ends the game. Finally a 4th queen wins £10000. What is the expected value of the game?

Wow, Im self studying higher apps too, from the leckie leckie textbook. I too have found multiple errors which I emailed Collins about, they replied saying they will fix it for later editions or something along those lines.

I recommend that once you've gotten to grips with the questions a bit, that you use the Dynamic Maths website to go over past paper questions. You can filter by subject, level, and topic/sub-topic, and there is always a link to the marking scheme, so I found it really useful (albeit for National 5 maths).

Hi,

I was tutoring a friend's child because I do that for a living! The applications course is new, I've never sat it and my maths and physics degree didn't cover everything that's in the applications course. A lot of it is working knowledge and formula/spreadsheet work. I was very upfront with my friend that there may be parts of the course id have to learn myself and that I may not be able to help but as it was, most of it was fine, I just had to workout if it was errors in the textbook periodically or if it was me!
