<p>For 105, you will mainly write several papers for which some research is needed, they are mainly 3 to 4 pages and sometimes a couple of longer ones. You must learn to write English well even for engineering. </p>
<p>The lower number for 101 and 102 does not mean they are easier than 105. Difficulty is about the same and you do almost as much writing for one of those 3 hour courses as you will for the 4 hour 105 course (in fact, some will tell you that 105, which is mostly occupied by engineering students because it is the required rhetoric course for engineering, is the easiest of any of those freshman composition courses).</p>
<p>105 is the required rhetoric course for engineering but you can substitute 101-102 for it (although you should check that with engineering because that is the kind of substitution rule that could be changed at any time), but 105 is designed to get engineering students their composition I requirement done in one semester The engineering schedule is usually “tight” throughout the four years, meaning there are so many courses you have to take that wasting one semester on a second freshman level rhetoric course could ultimately affect whether you finish in four years.</p>
