Working capability assessment (WCA)

Hi there ive just had my 2nd assessment in 3 month's for universal credit (WCA) and the difference in attitude from the first one was  unbelievable on my first assessment I got the usual assessor who wrote her report as if it was somebody else not me,that assessment is now at the appeal tribunal sovi don't know when I'll get my decision, DWP meanwhile decided to send me for a second WCA in 3 month's even though I've appealed against the first one but this time I got a qualified nurse who understood everything I was going through and was completely different from my first experience.i can't understand why I was sent for my 2nd assessment and can only assume it's because ive appealed the first one and they are trying to put it right before the tribunal decision.watch this space.
