"This occurred just prior to the exams when it was discovered that the newly refurbished labs were having some gas supply issues.
Also, there is an invigulator in the exam room to make sure no rules are broken and they seem to have no problem with results being given to candidates." While another said: "Thank God I revised Benedict's otherwise I wouldn't remember any of it!" Specimen results A parent who contacted the BBC said she was writing to the exam board about what had happened.An exam board is investigating suggestions that some teachers gave students hints about what questions would be in an A-level biology exam.Discussions in an online student forum ahead of OCR's A2 biology practical identified key areas for revision.And another recounted this experience: "In my last lesson my teachers made us do this practical practice sheet on the kidney - all about the different areas and what's in them etc so yeah I would say that is going to be the microscope question." A further student was equally definite about what would be in the question involving use of a microscope: "The microscope is on kidneys!That's for sure, my teacher would not lie." She later added: "Yes, she gave us a *MAJOR* hint so no reason to disbelieve her.One student who took the exam told the BBC News website that OCR issues a preliminary planning exercise a few months ahead of the exam each year, as part of the overall assessment, and the subject of that is always what subsequently appears in the real thing.As this year's was about kidneys it was no surprise when that came up. Let us know your thoughts using the form below: I think every candidate knew the kidney was coming up, those who didn't found out on OCR's forum website. They call it a "practical" exam, but you don't get any marks for the quality of your experiment only for how you understood it. Tom King, Bath I took this exam and yes my teacher along with all the other biology teachers hinted at what would be in the exam and yes it was Kidneys and food tests mainly.And the first question we were hinted by our techa that its got to do something with a mini water bath u have to make of ur own so is temperature and enzymes related to this?" And after the exam, one of the candidates wrote that the required drawings of what had been visible through a microscope had been "very hard" to do, adding: "However I gotta thank whoever said it was going to be on kidneys and foodtests!!
