To answer your question is 90% good that depends on what you use as a benchmark. Where did you take your part one course, who was your tutor.
I know some of the tutors are known for teaching the exam, in other words they spend two week getting you to learn 50 answers.
at the the end of the course you dont really understand why that is the answer you just know it is & that was what you had to remeber.
If that sounds about right then 90% is a crap score as all you had to do was learn to recognise the right answer for what is 50 easy question as all the tests are multipul choise.
If you was taught via the module and by your taking notes, you needed to understand what the question was asking and understand the right answer in order to select it from the 4 options.
you must have got 10 wrong & depends on what they were and weather you got it wrong as you rushed to get finished or did not know the right answer.
Getting 10 wrong is average but it is still 20%.............almost a quater of the questions wrong, so You could have done a lot better if you had read the module and understood the reason for the answer.
After all its the trade you have decided to take up, so if you want to be better than the bloke next to you .... you have to put in more than he did.
I see lots of lads reading the sun or falling asleep in the class ,as that is where the tutors go on about borring stuff, like heath and safety rubbish and its just some bloke waffling on about stuff that none of the lads understand or care about, such as Kilonewtons, forces and how how to avoid working at height. Its just like being back at school & most scaffolders have already screwed that up
Remember you only get out what you put in...........
Out of intrest what did the bloke next to you score?
