absolutely terrible do not use this website for your boaters test. completed it years ago and now i cannot purchase a replacement because they use their website and made it unable for me to see my previous courses. ive tried to call them, email, live chat, none of them will respond, what a waste of my time honestly. im not someone to make bad reviews but this is frustrating . don’t believe me? try and get ahold of them yourself before purchasing through their company. give them a call, you will be on hold until they close, give them a email they will not respond.
