By Lloyd Bathurst on 7/13/2024

Outstanding course. It goes into a lot of detail and is very well explained. I have bought several of Christopher's other courses and am working my way through them. The only negative is the lack of resources. I only received resources for Videos 58 and 59 - 4 resources in total. (Links to Setting up the environment). Even though there is a reference to resources throughout the course I could not find them anywhere. It would have been really useful. He mentions that links to further information are available in the resources to the video. These would have been beneficial as the links on the slides are not the URL addresses, (so can not be typed in manually) - these are hyperlinked behind normal text and (obviously) you can not click the hyperlinks inside a Video recording. I did send a message at the beginning of the course but has not yet been replied to yet. Hopefully, I do get a reply and resources are made available to download and use. I have bought many courses on Udemy. Christopher is hands down my favorite instructor so far as far as presentation, Knowledge of the content he is teaching, the level of detail he goes into, and how it is all explained so that it is easy to understand. Very highly recommended. Just a shame that the resources are not available to download as stated during the course. Very easy 4.5 out of 5. Would have been the full 5 out of 5 if I had gotten a reply about the missing resources but given time the reply might arrive and the issue will hopefully be rectified.
