history: I completed a qualifying test for a requester.  I am waiting to hear back whether or not I passed.  I hope I did. I completed some tests for qualifications.  I'm anxiously waiting to see if I passed. Was that for work?
current: Yes.  I'm trying to add on to my skill set.  Hopefully for better paying work.
next: I'm sure you are going to do great.  I really hope you do get a better paying job as a result.  Good luck!
