bite sized topics, building up in complexity. Somehow it took me a couple times to grasp selectmany and left joins etc. despite having enough experience in SQL. Would have liked to see a bit of PLINQ and a bit more on the let statement and for instance .Where(boolean && predicate) to filter based on parameters. I run into these at work all the time.

The course is well organized, the teacher is excellent, and she conveys an engaging passion that has given me the extra energy to tackle every challenge with dedication and a desire to learn. I will continue to follow the entire C# learning process, and my goal is to one day become as good as her, or at least come close. Thank you so much.
