Dreamlinerwannabe,
I passed the IT, in regards to the maths, I did Q1, Q2 and Q3 with calculations and then only had around 5 mins to do the rest of the other questions which I read through and made estimation with guesses.
My approach was quality over quantity, its hard to approach the maths test in quantity to try and tackle all 7 questions + sub questions with estimation/guesses, although it is possible!
As for the English, well my first language is English so I def had no problems with the English test.
You should have guessed the other questions, no harm in doing so.
