when I started plateauing I went back to the lessons and drilled specific question types (especially my weaker ones) until I started seeing the pattern to answering them. Once my drills were doing well I went back to full sections and full tests (which may dip a bit again - translating from specific questions to all types is a different game). If you really understand WHY you got a question wrong, you'll be less likely to make it again in the future. That said, some questions just get me and I'm okay with taking the hit on to save time, since I'm not aiming for perfect 😊
