Javi is an awesome professor who really tries to make learning Spanish fun and relatable. The class itself is fun and the information is extremely useful in speaking Spanish. My only complaint is that the homework is insane. Supersite is very picky about what you type and the homework and projects will take way too much time and feel like busy work- though the grammar ones do in fact help you learn your stuff if you pay attention while doing them. In all it's a good course to take, and since you probably have to take it anyway, I would recommend taking it with Javier.
