I work with students a lot so may be that is why I can talk with them.
It is not easy to find someone who are patient, seriously paying attention or keep a good time schedule to study together. The one who already got a job is harder to find free time or be disciplined in time table because of their private lives or so many relationships. They are possibly better than students in terms of being more experiences, more serious....
Student also has their own disadvantages to be a good partner to study with. They are young, they are easier to be distracted or you can get bored due to their limited experience. In that case, may be we need to talk to them as the one who is guiding them, teaching them. And If you can do that, I believe your E ability can improve alot.
When you want to be good at something, try to teach it
