Query: total waste of time

Please, do yourself a favor & buy a *serious* grammar book if you really want to learn the language -- I've been studying it off and on for years & this was a gift, I was glad I hadn't actually spent money on it...There really are no two ways about it while learning can be fun, it just can't be this superficial...My suggestion: try the Prego series...in bocca al lupo!Kathy
