Good for you that this strategy worked for you, but as others have commented, this relies on your ability to efficiently recognize classes you don't need to attend. The penalty for attending class when you didn't need to is a few hours a weeks spent in suboptimal times, but you can still work on other things at that time. The penalty for missing a class where you needed to be... well, that's your grade, buddy. I recommend erring on the side of conservatism, as it's easy and attractive to self-deceive into an overinflated concept of what we would have done with our time (hack vs TV+videogames+internet)
