UCAT: Abstract Reasoning

[kabir1803]

I'm struggling the most in this section. Shapes just make zero sense to me. Would appreciate some tips for AR! Thank you!

Personally, I was in your shoes around this time last year. I watched ALOT of youtube videos which allowed me to see the process to actually get the pattern. I would recommend Emil Eddy and KharmaMedic mainly for this on youtube. Also do a lot of questions but do them untimed in the start to get accuracy first. Speed will follow. Bets of luck

This is from the official mock B
Can anyone please explain what it means by 'L shape that is 2 layers thick'?

Two layers thick means one L on top of another L.
A 5x5 L shape needs 9 small squares (blocks?). Two layers = 18 blocks. But there are only 16 blocks in each group so not possible.

(You didn't show the question so I don't get why it gives six groups of 16 blocks in each set).

if you count the little blocks for each pattern in B they equal 16
which makes me even more confused... i really want to understand this pattern as it is an official AR question

I need to see the question itself to understand fully. You only posted the Answer Rationale.

By the look of it, I don't think it's intended you figure out mentally how to fit the B blocks around. The quick trick is in knowing 5x5 L shape two layers requires 18 blocks while you're given only 16. Thus "Set B" statement is not possible.

I agree with A1. If you take the time, you can rotate the blocks in each of set A to make the 4x4 shape but you can’t do that with the configurations in Set B despite there being the same amount of total blocks. That would be the ‘long’ way to do the question. But rapidly calculating that 4x4 = 16, but 9+9 = 18 means you can rule out B without taking that time.

Hello, could someone help me with this question from the official questions. What does the part that I highlighted mean? Won't you always get back the same number that you subtracted from the largest number if you do these steps? Thank you so much
