What These Lecture Notes Actually Are
Usmle Step 1 Kaplan Lecture Notes is a set of subject-by-subject review books published by Kaplan Medical, designed to condense the core information tested on the USMLE Step 1 exam. They cover biochemistry, microbiology, pharmacology, pathology, physiology, behavioral science, anatomy, and biostatistics. The format is deliberately streamlined, with bolded key terms, summary tables at the end of each chapter, and review questions at the back of some volumes. I used these during my own study period, and here is the thing most people do not tell you about them: they are not a standalone resource. They were never meant to be. If you treat them as your primary source of learning and skip the deeper materials, you will have gaps. That is not a flaw in the notes themselves, it is a mismatch between how people use them and what the exam actually demands.
Usmle Step 1 Kaplan Lecture Notes: How to Actually Use Them
The most effective approach is to read a chapter after you have already been exposed to the material through a video course or first-pass resource like First Aid or UWorld. The notes work best as a targeted review layer, not as the initial introduction. When I went through cardiology, I watched the Pathoma videos on heart disease first, then flipped to the Kaplan cardiology chapter to lock in the exact terminology and the high-yield tables. That sequence cut my reading time roughly in half compared to reading the notes cold. One specific problem I ran into: the pharmacology volume uses generic drug names alongside brand names inconsistently across chapters. In the autonomic pharmacology section, drugs like atropine and prazosin are listed with their trade names in the tables but not in the body text. This matters because the Step 1 exam does not test brand names, but seeing both formats can create confusion when you are trying to quickly scan for a mechanism. My workaround was simple. I ignored the brand names entirely and built a blank table in my notes where I only wrote the generic name, class, mechanism, and one classic side effect per drug. That cut my pharmacology review from about 4 hours down to maybe 90 minutes. Another practical tip that is worth mentioning. The summary tables at the end of each chapter are genuinely useful if you print them out and annotate them by hand. Digital highlights do not stick the way physical markup does. I found that writing contractions, memory cues, or corrections in the margins of those tables forced me to process the information actively rather than passively absorbing it.
There are real limitations to these notes, and you should know about them before investing significant time. The content is not updated as frequently as First Aid for the USMLE Step 1, which means some areas, particularly in immunology and microbiology, lag behind the current question style on the exam. Kaplan also tends to overexplain basic science mechanisms that the Step 1 rarely tests in depth. The biochemistry chapter, for instance, spends considerable time on detailed enzyme kinetics graphs that appear maybe once every few years on the actual exam. Reading those sections cover to cover will eat into your schedule without proportional return. If you are starting from zero and need a comprehensive foundational review before diving into question banks, the Kaplan lectures paired with the notes can still work. Just plan to supplement heavily with UWorld and First Aid from week one. If you are already well into your review phase, the notes become more of a secondary reference, and in that context their value drops significantly. Under those conditions, sticking to First Aid annotations and question bank review is usually more efficient.

The Niche Cases Where They Shine
There are a few subjects where the Kaplan notes genuinely outperform other resources. Behavioral science and biostatistics are two of them. The Kaplan treatment of study design, bias types, and statistical formulas is cleaner and more organized than what you get elsewhere. The tables on sensitivity, specificity, and predictive values are well laid out and include practice problems that mirror the style of actual exam questions. For these subjects specifically, using Kaplan as a primary resource rather than a supplementary one is reasonable. Microbiology is somewhere in between. The organism summaries are thorough, but the notes lean heavily on tables that can feel redundant if you are also doing Anki decks or SketchyMicro. I found myself reading the same bacterial characteristics in three different places, which wasted time without adding retention. The workaround here is to read the Kaplan chapter selectively, skipping the organism details you already know from another source and focusing on the sections that fill gaps in your knowledge. The anatomy section is a mixed bag. It covers gross anatomy and embryology, but the embryology content is somewhat dated in its presentation. The step 1 has shifted toward testing clinical correlations of embryological defects rather than pure developmental timelines, and Kaplan does not always align with that direction. I ended up using the embryology chapters sparingly and redirecting that time toward NBME practice questions that better reflected the current test format.
Practical Study Workflow
Here is how I structured my weeks when these notes were part of my routine. Monday through Wednesday, I would complete a block of UWorld questions on a specific system, review every incorrect answer, and annotate First Aid. Thursday would be dedicated to the corresponding Kaplan chapter, typically taking 60 to 90 minutes for a full read-through with active margin notes. Friday involved reviewing those annotated tables and doing any end-of-chapter questions. Saturday and Sunday were reserved for weaker subjects and full-length practice exams. This schedule used approximately 5 to 6 hours per week on the Kaplan materials. It is not a heavy investment, but it requires discipline because the notes can easily become a comfort activity, something to fall back on when you do not feel like doing the harder work of question analysis. I had to set a hard time limit on each chapter. Once the timer went off, I moved on regardless of whether I felt finished. Feeling finished is almost never the same as actually being prepared. Download links for these materials circulate in various places online, but I cannot provide those. The official publications are sold through Kaplan and major book retailers, and using pirated copies carries both legal risk and quality concerns with missing pages or poor scans. If budget is a constraint, buying a used copy from a recent test-taker is a practical alternative that saves a meaningful amount of money.
The bottom line is straightforward. These notes are competent, well-organized, and useful within a defined scope. They are not the answer to every study problem, and they should not be treated as one. Used correctly alongside a question bank and a current first-aid resource, they provide reliable coverage of the foundational content. Used in isolation, they leave you underprepared for the actual exam. The difference comes down to how you integrate them, not the quality of the content itself.
