Lecturio is one of the best resources for pathology currently. There are two things about Lecturio that I love. First is the bookmatcher. Like for pathology if you are reading robbins and you find it difficult to understand a topic then you can just go to bookmatcher, select Robbins, and give the page number where you are stuck. The bookmatcher will give you the exact videos that explain the topic on that page. This tool is very helpful. The other thing I love about Lecturio is its question bank. The questions given are really challenging and prepare for not only Step 1 but step 2 also.
