If you find some topics particularly challenging you might need to revisit them. You can use a technique called spaced repetition. Take this course today, then tomorrow, then after a further 3 days, then after a week, then after two weeks etc. Doing this will help cement syntax and terminology in your long term memory.
A technique you might want to try is to go through the course, just watching the videos first. Then retake the course again with the videos and assessment.
Another technique would be to keep retaking the assessments at using the spaced repetition method.
