<p>But note that if you skip Math 1B with AP credit or other college credit, be aware that Math 1B includes some introductory differential equations material that is not necessarily included in other high school or college calculus courses. You should self-study that material before the second half of Math 54, which picks up differential equations from where Math 1B left off.
