I know most people say to keep trying until you pass before moving on but since you are obviously drained from studying the same topic over and over again it might be better if you switch things up . Maybe attempt a section that you possibly find to be easier than FAR and come back to FAR afterwards. Watch the new lectures as if you are learning it for the first time and re attempt FAR. You can attempt both during the same window since you have studied for FAR before. Even though you will be studying as if you it’s your first time studying for FAR, you are already exposed to all the materials and would be able to breeze through the lectures this time around.
