<p>Do they have exams? I'm talking about chem 20b and physics 4AL. They have less units but I've heard that they are actually a lot more time consuming</p>
<p>I assume you mean chem 20L and phys 4AL.</p>
<p>20L: lab reports, midterm, and final. Although the midterm and final didn’t count for much of the grade.</p>
<p>4AL: just lab reports, no exams</p>
<p>also for 4AL there’s just the TA, no lecture. in 20L there’s lab with TA as well as lecture with professor.</p>
