Andrew's IB Maths Vault

Hi. Yes. Another month or two flew by before I could release this last bit of topic 1 - complex numbers. As mentioned in the document, I didn't include simple examples because y'all should be able to do them by the time you read this document. Don't be shocked that I didn't start with "adding complex numbers in Cartesian form". There are certainly one or two questions like that in the practice section if you do need a brief recap. Unsurprisingly these booklets take a WHILE to write, so I don't think I can finish the entire course this year. Will try to chuck out topic 2 and 5 though, alongside the mocks and the spreadsheet of topics I mentioned last time. Enjoy the summer, everyone not in Aus/NZ! :D I'll see y'all again soon! c: Andrew

Hey y'all! Sorry for the long delay. It's not that I'm particularly busy at the moment (though I should , and I have a design project due next week yay!). but I'm also working on some other stuffs  for you guys, notably, a chem mock. Yes, you heard it correct - it'll be coming... though I'm not sure it'll be on time for M22. I'm also writing some more sets of mocks that will be available for purchase soon, but considering the amount of studying I'll need to do for finals it might not be ready by the end of April. If you're interested, give me a DM and we could work things out. c; A little plug before we crack on: I'm available for private tutoring. Send me a DM to discuss about the details. Enough plugs for today. I'm back with the third part of Topic 1 Reviews: binomial expansion, simultaneous equations, partial fractions and combinatorics. The sections are way  shorter than my liking, but it's appropriate for a revision guide - do n...

Hello hello! After a successful launch of Revision Guide for topic 1.1 (sequences and series), I am now back with topics 1.2-1.3... after a month. I apologise for the long wait. This time around, we have proofs and logarithms. Some parts of 1.2 Proofs are only for HL students - these are clearly indicated in the booklet. Like the previous version, the questions are coded by my interpretation  of the difficulty using the scale on page 2. I have to admit that this booklet isn't perfect (there's a LOT more we could do with exponential and logarithmic equations), but due to the space restraints and that I don't wanna include questions that span several topics, I've "shortened" this section down to about 10-ish questions. Ladies and gentlemen, here it is: Good luck with your preparation kiddos. With 6 weeks before the first exam, the heat is on. Remember to take care of yourselves. c; Until next time, Andrew  Credits:  AdventurousAndrew#7499, unless otherwise state...

Henlo kiddos! Really hope everyone's doing great. Tis is the time of the year when N23s have barely started the course (and I see many of them are doing sequences and series) while M22s better start revising for the exams. Just a friendly reminder: unless you've been told explicitly  by your school that exams won't go forward, please  do yourself a favour and study NOW if you wanna do well. Due to popular demand (~40 votes in the Mocks server, not a small proportion) one of my focuses for this year is writing end-of-topic revision guides. I probably won't write these for EVERY SINGLE TOPIC , as some topics never  show up as a grade 7 question (I'm looking at you, correlation).  For more info re: the structure and the purpose of this booklet, read the second page, but here's a tl;dr: Different target audience - this booklet is aimed at everyone, including those shooting for a 7. Some questions are deliberately  set at that level. For more accessible questions, pl...
