I will be taking the WREB exams in about a month. I have read all the grading criteria and even watched the 1 hour demo video offered by WREB. The grading criteria for the Endo portion seems a little vague, can someone please advise? For eg. I took the CDCA, and for the endo access if you are 2mm away from the endo access it's a fail or major loss of points, for molar access if you are 2mm away from the marginal ridge it's a fail or major loss of points. I can't find any of that on the WREB grading criteria. The only specific guideline I can find is for obturation (1mm from the apex). Thanks in advance
