The vocabulary could much more useful
If the vocabulary could be sorted by mastery level and if we had a simple graph that shows the distribution of words across the three levels of master that would be very useful.
It would be a great incentive to work on a weaker words and see how the distribution improves.
Agree. So you could practice the extra words of your choice. At least words that are part of the fundamental vocabulary, say part of a set of most used 5000 words. They could be easily used by the robot to build a variety of simple sentences using the structure from the main practice test.
@naut yes, that would be very helpful. I think it would also helpful to have a general average for all words as a mastery score. From a learner perspective any tool that assist in improving what you have is valuable. If I could select a group of "weak" words (averages are OK) and then practice on them, it would be great. This is because if I am weak for say 200 words and I want to practice it is difficult to see the impact (the general score would help, but that is a longer term motivator - still important though. Thanks!
