<p>I’m pretty sure that number is actually 3 hours per unit per week. TO Courses are 4 units each. The amount of TO work will vary greatly depending on the week. I wouldn’t worry too much about planning study time at this point- it will vary greatly. Remember, you will probably be staying up later than you expect at this point. You may also have clubs or other activities when you don’t expect them right now. Don’t worry too much about having the perfect schedule at this point- things will fall into place when school starts.</p>
