And still people want to sign up!
Gavin, if you are remotely doubting your ability to pass a simple maths test then don't even bother. End of.
In other words, can you sit everything throughout the day even if you fail the first test at the start of the day?
I have no idea but I would say almost certainly no and why would you want to? Practice? Is it a case of one way or another, regardless of what the tests and people tell you, you are GOING to add to the HUGE pool of unemployed CPL/IR holders out there? Yeah why not, it's only you mum and dads home!
Sorry if it seems harsh. It'll be easy stuff like multiply 17 and 23. Subtract 126543 from 64325634 etc. If you can't do it, well, as Darwin said, only the strong survive. Don't resist nature.
