Are seminar breadth courses easy A?

<p>I'm planning to take a seminar breadth (2 units) on top of CS 61A, Math 1A, and R&C R2a. How hard is seminar breadth then (I assume 2 units/seminar = easy?)? From what I've read so far, it seems very interesting and easy. Of course I'll put my best effort to it, but I'm just wondering the difficulty.</p>

<p>Thanks!</p>
