I have done the ‘Write to The End of Your Novel’ It’s good to remind you of the basis for dialogue, suspense, etc. You get video and notes on each subject and then a 500-word writing task that you post on the CB forum. During the 6-week you will get feedback once from the course tutor so all the rest of the feedback will come from fellow students so quality of the feedback basically depends on who is on the course with you and how good they are at giving feedback.
I’m still in contact with some of the people who were on the course with me.
I hope this helps.
