There are a lot of options available to choose from, but in medicine you ought to make the best decision for better patient care. In this modern world you'll find that each and every person related to this field has their own websites, blogs, youtube channels, etc. In my opinion the most important factor to consider while choosing a particular resource over other, is to be aware of the authenticity of the content they deliver. Based on my experience here are some of those resources which you can best make use of -
Medscape - register for free and search for any topic on it; regularly updated Medical Students
Uptodate - great review articles by experts, but it's not freely accessible Smarter Decisions. Better Care.
ClinicalKey is an online tool by Elsevier where you can find all the books and journals published by them, along with clinical reviews on various topics. But to access you need to get a paid subscription for it. I am using it via remote access as a part of institutional subscription for it. StatPearls - review books and articles on various topics StatPearls - NCBI Bookshelf
NEJM Image challenge - great image based questions Image Challenge | NEJM
