okay, so I suck at tactics! not improving a whole lot. I am doing much better with lessons though. Now, don't go check out my tactics rating. But how in the world can I be improving so much in my lessons, and not getting any better at tactics?
The tactics score is meant to really measure your ability but the lessons score is just to motivate you to keep studying. I'd bet most of us have a lessons score hundreds of points higher than tactics.
