<p>It appears that the usual calculus sequence is 151-152-153-254 (four quarters for freshman calculus and multivariable calculus). The accelerated sequence is 161-162-163, with optional honors versions. There is a higher level of honors course in 190-191-264. Descriptions [here[/url</a>] – note general comment 3 at the top of the page, as it may be relevant here.</p>
<p>Presumably, the student in question has AP credit, since AP credit allows for skipping 151 (and 152 for a 4 or 5 on BC) and taking 152, 161, or 190 (see [url=<a href=“http://www.math.osu.edu/counseling/advanced_placement.html]here[/url]”>http://www.math.osu.edu/counseling/advanced_placement.html]here](<a href=“http://www.math.osu.edu/counseling/calculus_options.html]here[/url”>http://www.math.osu.edu/counseling/calculus_options.html)</a>).</p>
<p>It looks from [url=<a href=“http://www.math.osu.edu/courses/syllabi/]here[/url”>http://www.math.osu.edu/courses/syllabi/]here[/url</a>] that 161 is not offered in the winter quarter, so if the student has to repeat the course, he needs to take 152.</p>
<p>Just to make things more complicated, The Ohio State University will switch from the quarter system to the semester system in fall 2012.</p>
