<p>when i look at the courses for the summer, i see letters like h6 b6 and such on the left side of where it says the class is still open.</p>
<p>are these courses a continuation of the b1 h1 courses or something? i don't understand. i don't want to sign up for the wrong thing :P</p>
<p>also, when is the last day you can register for july-aug classes? will i be able to choose a summer course on the day of registration?</p>
<p>thank you for your time!</p>
