You are not getting much response here. Most of the QBs claim to have questions from the 2020 exams but in reality feedback is quite limited. For the bank that I manage we have gone through the old syllabus questions that were live in ECQBs 6/7/8 to see how they match the 2020 learning objectives and then marked them as suitable or not for the 2020 exams. This follows EASA's path - they say that about 75% of the 2020 exams use questions from the old syllabus. This cross-checking exercise betweeen the syllabi is fraught with problems as every judgement about whether a question complies with the new syllabus or not is entirely subjective. Early feedback suggests that in some subjects the EASA editors have applied a liberal interpretation, in others not. In terms of direct exam feedback some subjects are better addressed than others, for instance in Radio I have nearly 80 new questions, in Performance only three or four. In General Nav maybe 40, but they are unremarkable questions which you could answer without difficulty if you had done the course. Looking at fb user groups most people recommend Aviation Exam and ATPLQ; I would add to that the fb user group ATPL Theory Students EASA 2020 and the associated discord server. Discord, in particular, will show you how sparse solid feedback is. On the plus side the horrendous failures in the early exams seem restricted to a few schools and pass rates and marks are now coming well up, for instance I just had a msg from one student who passed his first 2020 module with Met 88%, HP 84%, Instruments 80% and Gen Nav 93%, which is nothing to sniff at. This pattern seems to be reflected across Europe. I do have some residual concerns about exams which not many people have taken yet, and therefore not much feedback. Performance is one of them. I should add that EASA have been maniacally reviewing their databases and are now at ECQB 2021 and ECQB 8, while the UK do not have the capability to change much and say 'there is nothing to be done'.
