Yeaa well, dont know much what is CAD, but you will encash the benefit of skill rating, imagine you can show case all your major and minor skills all with FULL star rating!!!
is a great feature dude, people can can be rated an overall rating and for each skill letting people with opportunity know true potential
the individual skill rating can help you earn from even a single skill
dat is, & much much more benefits come with skill rating... you can get more skills with time for taking courses and tests
