    Revision thread for the D1 exam.

    I have now included the Jan 2012 paper and model answers.

    I will start a new thread and include the paper and solutions to the exam on Friday (Friday night, if I am still awake after midnight).

    In the next few posts I will upload some past papers, mark schemes etc

    note - I will happily remove anything I have uploaded if requested by site admin.

    Thanks for the definitions, are they all the ones that we need?

    Effin hate D1, the algorithms are easy in themselves but the definitions and the need to be so neat and show everything is annoying.

    indeed, decided to teach it again. Surprisingly, quite enjoyed it. Edexcel D1 is much easier now Simplex has been booted to D2.

    Practice Papers
    Hi Arsey, thanks for the resources. Do you happen to have mark schemes for the practice papers and mock paper?

    Second this request!

    The solomon papers do have some stuff from old syllabus and possibly other exam boards since it doesn't say 'for edexcel' in the corner. but many of the questions are still relevant and a bit more challenging than what is likely to come up in the paper so definitely a good resource and practice for anyone who wants 100

    Thanks Arsey, especially for those defintions.

    Grde boundaries for 80+ is not really consistent compared to the core modules

    Any reason why?

    edit: looking at the jan grade boundaries, they are always higher :hmmmm: no silly mistakes afforded

    edit 2: i can't seem to open the defintions word doc, any help?
