I thought that intermediate was applicable to me, until I took to the sim for a self-check at RCB, found out that I was reduced to a beginner
BUT, having said that, my recent practices on the recently acquired sim [thanks to Mr.Sundaram], that I am able to quickly recall my past experiences and hopefully regain my self-demoted title soon
And coming to 'RC Skills', that would be of great variety of things, like for example, a builder [an expert like me
] or flier, or technician, or some of these combined or all of them.. Luckily for me, my knowledge is pretty good in electronics and mechanical of things, so technically I am an intermediate if not an expert
Edit: grammar
