"Just wanted to find out if you completed an online test ( basic checking and calculation) before sitting the stage 1 papers?"
I did complete this test but as to the results/feedback I havent received anything back at all. Nothing was mentioned at my S1 and to be honest it's a bit confusing. The NATS literature places emphasis on you completing this yet it seems to have no impact whatsoever on wether you can or can't sit your S1, so who knows...
The numeracy questions asked during the online test are different than the ones asked on the S1 (Speed Distance Time) which require you to solve 2 or 3 small calculations per question to arrive at a answer.
Looking at all the taster examples NATS gives you to prepare for these tests I'd say on a difficulty scale of 10 the examples are 2/10 - actual questions 6/10 - 10/10 (with a ticking clock factored in
)
Hope you do well mate.
