Getting Real Value from Physiology Examples Weekly
I've been using Physiology Examples Weekly for about three years now, mostly because I couldn't find a consistent source of clinically relevant physiology problems that weren't either too elementary or too dense to actually use during a study session. It's a weekly published resource that breaks down physiology concepts through worked examples, case scenarios, and calculation-based problems. The format has shifted a few times over the years — started as email-only, now you can grab PDFs or view everything on a web dashboard depending on your preference. To get started, you sign up through their main site at physiologyexamplesweekly.com. The free tier gives you one full example per week with basic explanations. Paid subscribers get the archive, which is where most of the useful material lives. The paywall sits around $12 a month, which is reasonable if you're actually going through the problems systematically rather than just hoarding them. The download process is straightforward. After logging in, each week's issue has a "Download Full Packet" button. It's a single PDF containing the problem set, worked solutions, and additional reading references. I've found it more efficient to download the archive immediately when available rather than waiting — the site sometimes runs into server issues on release day, and last year I spent two days locked out trying to grab Week 47 before my exam review window closed.
How to Actually Use This Without Burning Out
Here's the thing nobody tells you about physiology problem sets: doing them haphazardly is worse than not doing them at all. I learned this the hard way during my second year of residency prep. I was going through Physiology Examples Weekly issues in random order, bouncing between renal, cardiovascular, and endocrine problems based on whatever caught my eye that week. My scores on practice exams went nowhere for six weeks straight. I was recognizing the answer choices but couldn't work through the mechanisms under timed conditions. The fix was to follow the order they publish in and actually commit to the pace. One problem set per week, take your time, and when you get stuck, read the solution first rather than spinning your wheels for hours. The examples are designed to build on each other conceptually. Skipping ahead leaves gaps in your mental model that show up on board exams as seemingly unrelated questions you can't crack. I also started keeping a running error log — not a fancy system, just a document where I noted the problem number, what concept I missed, and the correct reasoning. After twelve weeks, reviewing that log took me about twenty minutes and immediately surfaced that I had a recurring blind spot around acid-base compensation curves. I targeted just that area for a weekend and saw measurable improvement on subsequent practice tests. That error log approach alone probably saved me forty hours of unfocused study time compared to my previous method.
Specific Problems and Edge Cases I've Hit
One persistent issue with the resource is that several of the earlier problem sets (weeks 1 through about 30) use slightly outdated reference ranges. The 2019 and 2020 editions still list normal anion gap as 8 to 16 mEq/L in places, and modern labs generally use 4 to 12 or 6 to 14 depending on the assay. This matters because some of the calculation examples hinge on those values, and if you're memorizing the numbers from those older sets for exam purposes, you'll be working with stale reference intervals. My workaround has been to cross-reference every problem set against the latest uptodate or Harrison's tables before committing the numbers to memory. It adds maybe ten minutes per week but prevents subtle knowledge decay. The newer issues from 2023 onward seem to have corrected this, so it's mainly a problem if you're diving into the full paid archive backwards like I did. Another edge case: the cardiovascular problem sets occasionally conflate compensatory mechanisms with primary pathology in their explanations. A specific example from Week 62 dealt with heart failure and framed the renin-angiotensin-aldosterone activation as purely compensatory without adequate emphasis on how it becomes maladaptive over time. For exam purposes this is a fine simplification, but if you're trying to build a mechanistic understanding that holds up in clinical reasoning, you need to supplement with additional reading on the neurohormonal chronic effects.

Common Pitfalls for Beginners
Most people who try Physiology Examples Weekly make the same mistakes in the first month. They treat it like a quiz resource where they should solve everything independently before looking at answers. Physiology problem solving is a skill that develops through seeing the reasoning chain, not through struggling alone. When you spend forty-five minutes on a single renal clearance problem and then look at the solution only to realize you made a unit conversion error in step two, you haven't actually learned anything productive. You've learned that you made a arithmetic mistake. Those are different things. A second pitfall is assuming the problem sets cover the full breadth of what you need. They don't. The resource is strongest on renal, cardiovascular, and acid-base physiology. Respiratory and endocrine sections are thinner and sometimes feel like afterthoughts. If you're preparing for comprehensive exams, you'll need to pair this with a dedicated respiratory physiology text and an endocrine review section. I used Costanzo alongside this for the first two months and it filled the gaps cleanly. The third pitfall is subscription complacency. Getting access doesn't equal improvement. I've seen people subscribe for four months and only work through eight problem sets total. The resource only helps if you're doing the work consistently. The weekly cadence is there for a reason — it mirrors the spaced repetition principle without you having to architect your own schedule.
When This Resource Falls Short
I need to be blunt about the limitations. Physiology Examples Weekly is not suitable for absolute beginners to physiology. If you've never taken a formal course or read a textbook like Guyton or Ganong, you'll read these problems and understand maybe sixty percent of what's being asked. The examples assume you already know the baseline concepts and are working on application and integration. I'd recommend going through at least one full textbook pass before starting with this resource, or working through it alongside a structured course. Another limitation is the lack of visual diagrams in most problem sets. Physiology, particularly cardiovascular and renal, benefits enormously from schematic representations. This resource is primarily text and numbers. You'll need to supplement with diagram-heavy materials if visual-spatial understanding is how you learn best. For advanced trainees — residents, fellows, people doing dedicated board prep in their final phase — this resource is solid but not indispensable. The problems are well-constructed but not particularly challenging beyond a certain ceiling. If you're scoring above ninety percent on practice exams already, you might find yourself bored within a month. In that case, UWorld or Amboss question banks would be a better use of your time.
Alternative Approaches if This Doesn't Fit
If you try a couple of weeks and this format isn't working for you, there are alternatives. BoardVitals has a physiology section that's more clinically integrated and updates its content more frequently. RxKinetics focuses heavily on pharmacokinetics and pharmacodynamics, which overlaps with physiology but isn't the same. For pure physiology problem solving, Pathoma's physiology companion material is concise but limited in scope. The one resource I'd specifically point to if you're struggling with the calc-heavy problems in Physiology Examples Weekly is BRS Physiology by Linda Costanzo. It's older, sure, but the problem sets in chapters four through ten mirror the style and difficulty level of what this weekly resource is trying to teach. Using both together for a few months is probably overkill for most people, but if you're weak on calculations specifically, that combination covers it comprehensively.
Long-term Retention Strategy
The most important thing I've figured out about using this resource effectively is that the problems need to be revisited. I go back through each completed week's set once at the four-week mark and once at the twelve-week mark. The first revisit takes about fifteen minutes per problem set — just glancing at the problems and trying to reconstruct the solution path in my head before checking. The second revisit, three months later, is more selective. I only look at problems I got wrong originally or that I felt uncertain about during the first pass. This spaced revisit approach has kept the material fresh for me across a nine-month study period without requiring daily grinding. It's not glamorous. It's just consistent, deliberate practice with an eye toward retention rather than completion. That distinction matters more than most people realize when they're trying to prepare for comprehensive physiology assessments.
