You can read other posts on this topic. There are no magic formulas. You must learn the material before you can review it.
Some things I've been told:
-Study major diseases that are encountered clinically. Avoid memorizing the eponyms of obscure diseases. Rare diseases are important if they have been well-studied, or highlight a scientific concept.
-If you are weak in one subject, then it may seem like the bulk of questions are from your weak subject. This is because many questions are multidisciplinary and may require you to derive information from several fields.
-Do not only study passively. Rewrite, take quizzes, make drawings, annotate FA, etc.
-Avoid memorizing cliche eponyms or buzzwords, unless they help you understand the concept.
-Make sure you understand the scientific concepts behind each diseases process.
