Why maths here is built differently · and what Paper 2 changes
Maths is not like your other subjects. In Biology you can learn Topic 7 without Topic 3 and still do well. In maths, almost everything sits on top of something older — every equation needs negative numbers, every rearrangement needs fractions, every graph needs both. When maths feels hard, it is very often not the new topic at all. It is a loose brick further down.
So we are not starting at Chapter 1 and marching forward. We find the loose bricks first, relay them, then build. That is slower for about three weeks and considerably faster after that.
This is also the opposite of how the science sections here work. Physics, Chemistry and Biology throw hard papers at you deliberately. Maths will not do that, not yet. Difficulty is only useful once the ground underneath is solid.

Every idea on every guide is taught the same way: a fully worked example, then the same kind of problem with the last step blank, then the last two blank, then one entirely on your own. You are never staring at a blank page, and never just watching someone else do it — which is the trap with worked solutions, because watching feels like learning and is not.
Each guide then ends with a mixed set with no labels. Deciding which method applies is the skill ordinary revision skips, and it is most of what an exam question is really asking.
