Loosing XP?

Question

If you get a question wrong on a lesson and press try again and get it right, do you loose the xp you would gain if you get it right the first time? (If you get xp by answering questions)

Answer 1

You won't, but users have reported not getting full course XP upon completion if too many errors were committed. The exact XP loss is vague.

Answer 2

I strongly remember losing 1 XP for wrong answers in courses.
