The question help videos are so outdated that they don't even show how to use the software you are supposed to use with some problems. The book tells you to do things one way, though it really does not give useful examples and certainly does not have examples of how to use the required SALT program. Then the teacher will tell you to do it another way, and the videos tell you to do it a third way. There is no useful explanation of how to use the SALT program. If you have a choice, burning your money would be quicker than buying this software.
