My name is Ray Chambers. I'm a specialist in computing and have a first class honours degree in computer science. I'm currently the lead teacher of computer science at Brooke Weston Academy in Corby Northamptonshire. I have been teaching for roughly 8 years and I thoroughly enjoy my job. In 2015 I was fortunate to win the Pearson National Teaching Award for innovative use of technology. I also won the BAFTA for mentoring young coders.

I have used the last 4-5 years of A-Level computing questions to find questions on floating point binary. I have compiled them in a 50 mark test which will test the students on their ability to do the following: -

- convert from denary to binary
- convert from denary to floating point binary
- convert from floating point binary to denary
- normalise floating point binary
- compare floating point binary numbers to check accuracy

Answer sheet has been provided against the spec so that you can see where it's possible to gain marks.

I used this against the current grade boundaries to assess where they're currently at.
