Bristol bank....why?
Hi,
I have noticed that when you are going though a subject on Bristol question bank, if you get a question correct you will receive less percentage than the amount you loose if you get the next one wrong.
For example I just made one correct and from 85% I got 85.1% while the next one was answered wrong and got down to 84.3%.
How on earth does this work?

Maths
If for example you had taken 100 questions and out of those you got 85 correct you would have a mark of 85%.
If you got the next one right you would have 86/101=85.1% (1d.p of course)
If the next answer was incorrect you have 86 correct out of 102 questions, making 84.3% (1d.p)
Its not a trick just the way percentages are calculated.
As long as your marks are over the magic 75% don't worry too much.
