Yes, you can look at your notes and any other information source when you complete your exam but directly copying or pasting from web sites is not permitted. Everything you write in your exam must be your own words, or words from the case study.  However, if you use any information from another source, you will be able to list the source at the end of your answers, there will be a box for this. You do not have to give full references just list the source name e.g., HSG65, CSP Course notes, HM Fire Guide on Factories.  Reproducing what is in your course notes word for word will not answer the questions. By submitting your answers, you are agreeing that what you submit is your own work.  If you copy and plagiarise this will be deemed malpractice and you could have your results voided.
