Think twice before signing up for this. I wasn't even on there a month and got paired up with "Mick" the 6'2" Mechanical Engineer who was half-Italian, college educated in Indonesia - lost both his parents (his father was a gold merchant) in the 2004 tsunami and was widowed (never did tell me how he lost both his wife and son). He was here in Texas mining (yes that's what he said) for oil ... needless to say I reported him and they yanked him. Or how about the guy I did actually meet who said he was divorced well ... he was almost divorced. Chemistry naturally doesn't REFUND any $$ but with luck like that I would think they'd feel ASHAMED charging me but no not them.
