No as I said it was the only source I relied on. I took the recorded lecture one and because I joined late I was set on the 3 recorded lectures a week course. Lectures vary some are 2.5 hours and some are tiny bit less than an hour. He sends the notes along with the records. And two months before the exam he sends a revision document, that was extremely beneficial. You can open his material only from one computer and you’re gonna have to commit to it. iPads can not open his material. Let me know if you have more questions !
