Stage 1
Had stage 1 today. I can't say too much but here we go.
Out of around 38 only 7 made it past the first test. To be frank, this is insane.
If you learn the handout as you are told to do you will pass. The maths questions are basic and you should be able to have at least an educated guess if you are not to hot on maths. My only real advice is that if you have not learnt the handout come test day ask to rearrange to a later date. This was also the advise of the assessor.
As to the other tests, I found them pretty tough. I managed 39/50 on diagramming. I know I was being too careful, I even triple checked an answer which takes up too much time. The best advice for that is don't doubt yourself. If you are 80-90% sure that is fine, move on.
I answered 39/40 cubes. I felt strong on most of these but by the last 2 or 3 I felt my brain melt and drip out of all the holes on my head.
I would say I am a pessimistic 50/50 so I will let you know.
Good luck to those that have yet to try, and as above, learn the booklet.
