There are four kinds of PLE taker, whether you are a medical student, a clerk, a PGI, or taking the exam again.
Some have a lot of medical knowledge, but no study schedule.
Some have a detailed study plan and a lot of study materials, but have never done a single practice test.
Most are somewhere in between. Studying on and off, with no idea whether it is enough, or whether they are even doing the right things.
This tells you which one you are, and the one thing to do next so you can pass the PLE.
