Does re-doing a lesson increase the number of points I get?

[Lord_Stanley]

I tried re-doing a lesson because I did poorly, but I did not get any more points the second time around, even though I did better. Is this the way it is expected to work.

No. You get points for completing the lesson, not on how well you did on it. You have 3 "lives" to get through the lesson. If you don't make it, you just keep trying until you get it.
