However, unless you are possessed of a decent puzzle-solving intellect (and like crossword puzzles adventure games get easier to work out the more one plays them) or have a very high tolerance for trial and error, you may find that occasionally consulting an online walkthrough will ease frustration.
Few of the consulting companies offer introductory courses online making it even more accessible, but I recommend taking the hands-on courses face-to-face with other participants to make the learning experience real life and pertinent to your current business environment.
