Is there a way to increase XP from a completed course?

Question

For instance, I have 183 XP in the completed SQL course. I assume this is because I got some questions wrong the first time. I didn't use any hints.

So, is there a way to go back and get a perfect score? If you get a question wrong, even by accident, your XP score for that course is ruined forever?

Answer 1

SQL challenges are not available yet!

Answer 2

So if I challenge someone to SQL, it will raise my SQL XP if I win and lower it if I lose?

Yes you can ! All you need is to challenge your pears with the very same language that you have completed.
