UCSC offers four different two quarter calculus sequences. Each sequence is optimized to provide you with the mathematical knowledge and skills you’ll need in your future courses and careers.
Placement tiers for calculus
Each calculus sequence has its own placement tier requirement. The 19AB sequence makes extensive use of trigonometry, while the 20AB sequence emphasizes the abstract theory of functions, so these sequences require stronger math preparation and higher placement tiers than the two 11AB calculus sequences do.
If you’re not yet eligible for the course you want to take, work in your ALEKS Learning Module and reassess to improve your placement tier.
You don’t need to take the highest numbered calculus sequence you’re eligible to enroll in. It’s usually best to take the sequence that’s recommended for your major.
