I only realised this when I compared how the so-called "best mathematics book in the market" (New Concise Project Maths 4&5) explains quadratic inequalities to how Khan Academy does them. They are not even comparable: the book has this nonsense approach about "changing the inequality sign to an equality sign" and this "testing for 0" that is completely unexplained. I had DONE inequalities before in TY using my teacher's method and had a firm understanding of what is happening and it took me a good 40 minutes to figure out what the hell any of this means. It only showed examples where the inequality sign was less than equals too! And only examples of where the "testing for 0" actually was true, making it that much more confusing. And all that for a method that tries to completely disregard the properties of an inequality by "making" it an equality. Whereas Khan's approach was much more simple, it actually tells you that when the two multiples must be both positive or both negative if it is greater than 0 and the converse. Seriously, though, how did this come out of testing? I've already encountered many problems with book regarding inaccurate answer keys and I never used the textbook for EXPLAINATIONS until now. Thank God I haven't! Is this really supposed to be the best maths book on the market? If that's the case, I'd be surprised if the others even taught the content on the course, let alone in a coherent manner. Anyway, wow, what a rant. I normally don't get this passionate or anylatical over these kinds of things. But I just had to put it out there, I mean, could abysmal textbooks be one of the reasons why so many people find

It's kind of funny how similar everything is to the JC, study patterns, subjects, everything. I know myself that I studied too much for the JC, but still. Also, is my class really behind in Maths? We've only done the following: Algebra Function Theory Logs and Indices Inequalities Numbers That's it. I'm seriously worried now, since I'm finding the class so easy that I'm almost certain that we're not covering things quick enough. Should I continue to go ahead of the class (I'm almost done trigonometry, geometry, halfway through complex numbers, done bits of probability and statistics and plan on tackling calculus very soon), or should I just relax? If anyone else is in fifth year here, how far have any of you gotten in Maths (HL)?

Now in 6th year we will have the course done a week or 2 after the mocks so I'd say you have nothing to worry about, and it seems you've gone a good bit ahead so yeah your grand. I would probably advise to take it handy with study wise cause you'll just be fed up come next year. I know personally I'm sick of it already and in reality I havnt even started any study yet. If you do continue to plow on though I'd advise you to work on exam questions and not book questions, much more beneficial.
