A couple of comments on the Mastee''s 100T course and exam. Fully agree that a 5 day course, 8 hrs per day is just too much, too fast. If you''re lucky you''ll pass but in 3 wks will have forgoten most of the mat''l. If possible, find a course given over an eight to ten week period - 3 hrs a nite, three times a week. It''ll give you time to read, digest and assimilate the matl because there is a lot. A good course will NEVER "teach to the test" - if the material is taught correctly and you have time to study, the test takes care of itself. Re: texts - Bowditch certainly the bible but is more than needed at the 100 T level. "Wing" is a good book - a little brief on text but has the questions both printed and on a CD-ROM that comes with it. Be sure to get the Coast Guard''s "Navigation Rules" (COMDINST M16672.2D)- a white covered paperback that most marine stores have. Much easier to use than reading them on a screen. The only section of the test that requires a 90% is Rules of the Road - the other three (Chart Plotting, Nav General and Deck General) require 70%. It is a lot of work, but it''s worth the effort, especially if you choose a good course with good people and not simply a "mill". Good luck.
