This is a good corrective to all the anime that are filled with model students; it shows that there are Japanese students who just get by in class and get into trouble with their teachers, too, without being complete delinquents. While the tone of Super GALS! is sometimes serious, it's primarily about having fun, living life to the fullest even when you've already spent all of your allowance, and being true to your friends and your favourite place to hang out.
Worth a look.
