I find it silly that when I get 18 questions in a row, I get like, four experience, but when I get 5/20 questions right, I get five.
Anyone think this need rebalancing?
The only reason this is happening because those "18 questions in a row" are from a 4/5 skill. The amount a skill is strengthened affects your XP earned. In timed Practice, your XP corresponds to the questions you got right.
The XP acquired changes correspondingly with the strength of the skill, not questions right in a regular practice.
In a Timed Practice, the amount of questions you get right will equal your XP (1 question right=1XP)
