Hi. A colleague of mine is going for chief mates orals April next year and before he goes to the orals prep class he (and i) were looking for any online resources which may assist passing.

Can anyone advise of any resources...I'll be doing mine in a years time approx so plenty time for me. Are their any books/publications which are good? Are their a bank of chief mates orals testimonies anywhere (i found OOW really useful)? Any other online resources available...free or worth paying for?
