Lower Division Credits:
* Generally for first and second-year students: These credits are typically earned in introductory courses that cover foundational concepts in a particular subject area. These courses often fulfill general education requirements.
* Introductory courses: Think introductory biology, general chemistry, freshman-level composition, etc. They focus on building a basic understanding of the subject matter.
* Lower numbered courses: Often designated by course numbers in the 100s or sometimes the 200s, depending on the institution's numbering system.
Upper Division Credits:
* Generally for third and fourth-year students: These credits are earned in more advanced and specialized courses that build upon the foundational knowledge gained in lower-division courses.
* Specialized and advanced courses: These courses delve deeper into specific topics within a major or minor, requiring a greater understanding of the subject matter and often more independent work.
* Higher numbered courses: Usually designated by course numbers in the 300s and 400s. They might include advanced seminars, research projects, capstone experiences, or in-depth studies of specific areas within a discipline.
* Often prerequisites required: Many upper-division courses will require successful completion of relevant lower-division courses as prerequisites.
Key Differences Summarized:
| Feature | Lower Division | Upper Division |

| Course Level | Introductory, foundational | Advanced, specialized |
| Course Numbers| Typically 100-level or low 200-level (varies) | Typically 300-level and 400-level (varies) |
| Content | Basic concepts, broad overview | In-depth study, specialized knowledge |
| Difficulty | Generally less demanding | Generally more demanding, requiring more independent work |
| Prerequisites | Fewer prerequisites | Often requires completion of lower-division courses |
It's important to note that these are general guidelines. Specific requirements and course numbering systems can vary significantly between institutions and even departments within the same institution. Always check your university's catalog or academic advisor for precise details on their course numbering and credit classification system.
