Getting Your Hands on the Physiology Weekly PDFs
The Physiology Weekly PDF is a compiled set of practice problems and summary notes that circulates among medical and graduate physiology students. Most people find it through departmental mailing lists or upperclassmen who share Google Drive folders. It isn't officially published by any textbook company. It's student-made, which means the quality fluctuates from week to week depending on who compiled it that cycle. I started using it during my second year when my professor suggested the group for extra problem sets. The first few weeks were messy. Pages were misaligned, some figures were cut off, and the answer key for week four was missing entirely. I learned to cross-reference everything with Guyton and basic diuretic physiology before trusting the key. One specific issue I ran into: the renal physiology week had a calculation for GFR clearance that used the wrong molecular weight for inulin. The final number was off by about 18%. I flagged it in the shared doc and the next week's author corrected it, but that's the kind of thing you need to watch for. Don't just accept a number because it's in a PDF.
How to Download Pdf For Physiology Weekly
The most reliable way to get the files is through the university shared drive link that gets posted every Friday afternoon. Students who maintain the account rotate access, so the link sometimes expires mid-semester. I keep a local backup folder and rename each file with the date and topic when it arrives, like phys_week12_cardio_2025-03.pdf. This matters because the naming convention changes without warning. Here is the practical process. You will see a Drive folder with weekly subfolders. Each contains a problem set PDF, a solutions PDF, and sometimes an optional reading list. Download both the problem set and the solutions together. Open them side by side in a PDF reader that supports annotation. Highlight the problems you get wrong, then compare your work against the solution step by step before the week ends. The window where the material is useful is roughly seven to ten days after release. After that you are studying old problems and you have newer ones coming in. A few details that are not obvious from the surface. The PDFs are usually generated from LaTeX sources, which means equations render cleanly, but sometimes the table of contents hyperlinks break if you open the file on a phone. Use a desktop or tablet. Also, the file sizes are deceptive. A single week can be 4 to 8 megabytes because the solution sets include annotated diagrams. Plan your storage accordingly if you are archiving by semester.
What Makes These PDFs Worth Your Time
The problem sets are not trivia. They are mechanism-based questions that force you to trace a pathway from receptor to response. Week eight on acid-base balance had a case where a patient presented with mixed metabolic acidosis and respiratory alkalosis, and the solution required you to calculate the anion gap, assess the delta ratio, and then determine whether a third disorder was present. That is the actual skill level these materials target. Most standard textbooks give you clean single-disorder examples. The weekly PDFs give you the messy ones because that is what you will see on clinical rotations and board exams. The answer explanations are where beginners waste time. Some weeks, the authors skip steps and say "clearly the compensation is adequate" without showing the winter formula calculation. I once spent twenty minutes trying to reverse engineer their conclusion before realizing they had simply assumed full compensation without verifying it. The workaround is to always redo the calculation yourself rather than accepting the stated conclusion. Another quirk: certain weeks include problems pulled from older editions of costanzo or ganong, and those older editions use slightly different reference ranges for values like serum potassium. If your class is using a newer edition with updated norms, flag the discrepancy immediately. It is easy to lose points on an exam for using outdated reference intervals without noticing.

Limitations You Need to Accept
These PDFs are not a replacement for a primary textbook. They are supplementary problem practice. The coverage is uneven. Cardiovascular weeks tend to be thorough, but endocrine and neurophysiology weeks can be thin, sometimes containing only three or four problems with minimal explanation. If your curriculum requires deep endocrine coverage, you will need to supplement with another source like BRS Physiology or a dedicated question bank. The compilation also lacks peer review beyond the student authors themselves, so factual errors do occur, though they are usually corrected in subsequent weekly emails if reported. I recommend treating each week as a timed self-assessment rather than a casual read. Set a timer for forty-five minutes, work through the problem set without notes, then spend another thirty checking and annotating. This approach takes about an hour per week and usually improves retention more than reading the same material passively for two hours. The material becomes useful only when you actively retrieve answers under constrained conditions, not when you read through solutions after the fact.
