PW

Hey people, just an initiative. Please help to post questions for OP on the google docs (see link below). Maybe you'all might also want to upload your slides/abstract here or on the google docs so people can ask relevant questions. Let's try our best to get the entire class to pull through PW OP. Thanks.
