If I'm doing Spanish I generally achieve 100%. French, not so much. Depending on the exercise I get anywhere from as low as 1 all the way up to 20, but it's most common that I run out of time and have a very low score. I've had to move back to untimed practices for French because I'm just not good enough yet to handle timed practices.

I haven't used it in a while as I'm learning a new language at the moment. However, I seem to recall usually 17 to 20 questions right. Timed practice is usually good for skills that need practice but are very boring/repetitive the regular way.

17-19, but it depends on the day. You may not always be in the mood for timed practices.

Previously 16-20, but after they made it faster during the rewrite, I've regularly scored 0s, 20s and everything between even in the same language.

It used to be fairly easy because the spoken questions gained you enough time to think through the more difficult questions. Now I find that one mistake puts me under so much time pressure that I lose more through typos and an early mistake will cause me to end very quickly.

I find it very good for having to answer without thinking in English though.

Mostly between 16 - 18. I think the timed quiz contains 20. And my answers are 'wrong' just because I forgot the 'e' in 'the'! I almost never ran out of time, and take the test at just a slightly higher-than-normal pace.

usually 15 is the minimum for me

As for English I usually get 20/20 (although I sometimes get 19 or 18 out of the full 20). In French it really depends on the 'mood' I am in and which lesson it is. (Generally 5 to 15 I think)

It varies. Usually I'm in the 15-20 range, but today I had numbers and couldn't type them fast enough and got only 7.
