Champion Tactics with GM Wolff

Misplaced Pieces Course is a bit off with its ratings.  Perhaps the author is unfamiliar with Chess.com rating levels.  First two problems are terribly simple but then it just shoots right up.  

Lessons 4 and 5 must be over 1600, putting this entire course at a different level.  Could someone flip through and fix them?  Thanks.

Lesson 17 seems to be buggy. If you do anything other than take the queen after queen takes bishop, it says that the move is not legal. Yet there are plenty of other legal moves.

Which course are you referring to Mark? The Misplaced Pieces course only has 16 lessons.

AfafBouardi, please feel free to suggest new ratings for what specific lessons should be and I will be happy to consider making the change.

oops its Champion Tactics with GM Wolff - Interference lesson 17

Patzer...I don't mind leaving a note when I run into a problem whose rating is off...but as I try to do courses from easiest to hardest.... when I'm going through a course and each problem is clearly way out there...I begin to feel like I'm not studying the course but instead exasperatedly identifying the difficulty level.

Before releasing courses, maybe have a couple people of varying levels go through and do the problems?    I think you have staff that is of all chess playing levels...so a 1500 level player could tell you what's way over their head. 

Thanks mark_joshi. I have now added move responses in that position for all legal moves.

Thanks AfafBouardi. We do try our best to correctly categorize the difficulty of each problem. Please note in some of the Chess Mentor courses the lessons will not go in order of easiest to hardest.

in lesson 16 of misplaced pieces, it would be useful to have a little more discussion of why knights takes e6 and d5 are bad. (I eventually worked it out...)

ya. I got 73% cuz I thought it was knight takes d6

Yes, a small course like Misplaced Pieces should be extra intensive to be beneficial.

Thanks for the feedback! I have added two incorrect move responses for these two moves in lesson 16 of the Misplaced Pieces course.

lesson 17 interference. after QxB it is check

I liked all GM Wolff tactics courses. It is always pleasantly surprising for me when GMs of such high quality understand the difficulties of average players.  Anyway, just wanted to leave my positive feedback of the course and appreciation for the staff's work.  

In lesson 33 of champion tactics -- back rank

I rejected R c8 on the grounds that I thought that black would do Q x d7

Why doesn't he?

I think GM Patrick Wolff tactics courses are really good. Its helpful to keep repeating one main tactical motif in many situations until it becomes easy. Normally good at tactics anyway, but these courses remind me to keep looking at the small details in real games.

I'll leave another comment here just to check if gets picked, as there seems to have been some replies to these issues, and this does report to the same courses.

There seems to be a problem with one of the Champion Tactics with GM Wolff - Interference is giving me a complete percentage of 95.65% when there are no more lessons available. Lesson 14 is not showing, but it is being accounted for the total.
