Hi PH community, As a self-learner I am always faced with a big obstacle: How to set the learning goal and find the suitable and high-quality learning materials? As a result I spent hours on browsing Coursea, Edx, or MIT Open Courseware just to make a decision what to study. This needs to be streamlined, so I built Cogak. Cogak is a website that guides you to open courses from the top universities around the world: [cogak.com](https://cogak.com/) It's a great tool for self-studying Computer Science topics (it currently has computer science courses only, but other disciplines are definitely in the roadmap). The [topic page](https://cogak.com/topic) categorizes courses from different universities based on the topic. By looking at the topics, you can quickly get a big picture of what the top universities teach to their students in this discipline. Also, the course page summarizes the availability of resources for you, so that you don't need to spend time digging into pages to excavate usable materials. Cogak is the advisor of your self-paced online learning. If you love self-studyiing like me, please share Cogak and let me know what you think! Stephen Lau Maker of Cogak

Nice
