How to Refresh Expired A&P or Physics for Sonography- If your anatomy and physiology or physics credits have aged past your program’s recency window, you don’t have to start over — you just have to refresh. Expired prerequisites are one of the most common obstacles for career changers and returning students, and they’re also one of the easiest to fix once you know the move. This guide walks through exactly how to refresh expired science prerequisites online, how to choose what to retake, and how to time it so you’re back inside the window before your application cycle.
Before retaking anything, pin down which courses have aged out and which still count. Most programs apply a recency window of about five years to science and math — A&P and physics most of all — while general education (English, speech, psychology) usually doesn’t expire. For the full rules, see sonography prerequisite recency rules.
| Credit | Likely status | Action |
|---|---|---|
| A&P older than the window | Expired for most programs | Refresh A&P I and/or II |
| Physics older than the window | Expired for most programs | Refresh physics (with lab) |
| Math | Sometimes time-limited | Confirm; refresh only if required |
| General education | Usually still valid | Keep — no action needed |
The goal is targeted, not total. You retake the specific expired courses — not your whole transcript. For most applicants that means one or two sciences:
Refreshing an expired prerequisite is the textbook use case for self-paced, online, regionally accredited courses. You’re not seeking a degree — you need a specific, transcripted, lab-bearing course completed on your schedule, ideally before a deadline. Self-paced format lets you move quickly through material you’ve seen before, and an official transcript is what your program needs to count the refreshed credit. Confirm the course matches the credits, content, and lab format your program expects.
Confirm before you enroll. Recency windows, which courses must be refreshed, whether a lab is required, and whether an online refresh is accepted all vary by program, and transfer acceptance is never automatic. Confirm with the registrar before retaking anything. We don’t guarantee admission or transfer.
Career changer working through an older transcript? Pair this with career change to sonography: where to start.
You retake the specific expired course — usually A&P or physics — from a regionally accredited provider, with a lab where required, so it posts to an official transcript inside your program’s recency window.
No. You refresh only the courses that have expired, typically one or two sciences. General-education credits usually still count and don’t need retaking.
Yes — this is one of the most common reasons applicants use self-paced online prerequisites. Confirm the course’s credits, content, lab, and accreditation match what your program accepts.
Self-paced courses let you move at your own speed, so a single science can often be completed in weeks rather than a full term. Physics is usually the slower one to source online.
