Help a Fellow High Schooler with Spanish please?

<p>I take Spanish. In fact this is my fourth year studying Spanish. I often fall asleep in class, so I basically end up self-studying for all my Spanish tests with varying results (60-96%) (yeah... that's bad.)</p>

<p>Anyone know any good websites for Spanish exercises (with answers, answers AND explanations would be best). My teacher (the same teacher I've had two years in a row) suggested these two websites last year:
1. Colby College Spanish Grammar Exercises
2. Trinity Spanish Exercises</p>

<p>Those are the only two I know. They're good, but the amount of practice I can do on those websites is limited. </p>

<p>And just putting this out there, I've been improving with the falling asleep in class. I nod off for a few seconds out of 40 minutes now, but I can still use the extra practice. :)</p>

<p>make a friend in class and ask to borrow their notes once in a while, lol. And I thought I was the only one who fell asleep in classes and self-studied (did this in Stats all year long) :). Looking through the Spanish book is usually most helpful though.</p>

<p>Conjuguemos is great for fast verb conjugation.</p>
