For example, [physics 1](https://students.technion.ac.il/local/technionsearch/course/114051) Requires [Calc 1](https://students.technion.ac.il/local/technionsearch/course/104003) or [Calc 1m](https://students.technion.ac.il/local/technionsearch/course/104018), but course [Calc 1m1](https://students.technion.ac.il/local/technionsearch/course/104041) 'encapsulates' that course.
