Work those out one figure at a time and matrices 5 and 6 fall out.
There are no options to work backwards from — you type a value for every variable. So the whole subtest is substitution and elimination done in your head, in order, without writing anything down.
Only two deduction rules exist, and one of them does almost all the work. Most of these are solvable in one or two moves once you know which cell to look at — and you never need to fill in the whole grid.
The first General Academic Module lecture. Nobody expects you to know physics going in — the text hands you every rule. This one teaches the five its questions run on: pressure with depth, floating, why air shrinks when water will not, the ten-metre suction limit, and why a wide ship leans less.
Nobody expects you to have studied logistics — the text hands you the model and one whole question does nothing but check you read its four assumptions. Then two costs pull in opposite directions, and the total has a floor between them.
The one General Academic Module text with no formula in it at all — it is purely about reading precisely. Everything hangs on one split: does a factor relate to an outcome, or how does the outcome come about?
The last of the four official practice texts, and the deck is up before the recording is. Vectors in three dimensions: adding them, the two different products and what each one gives you back, and the triple product that falls out of both.
Sit a mock first, check your progress for the subtest that cost you most, then watch that lecture. Watching cold works too — it is just slower, because a lecture lands properly once you have already lost marks to the thing it is about.
