CDT exam passing score and which chapters to actually prioritize

Your 68-70% after five weeks is a solid place to be. Most people find their scores jump in the final three to four weeks when everything starts connecting. Keep the daily practice going and you'll likely land at 75-78% by exam day.

The procedural section on my exam was lighter than expected — maybe 15% of questions. Don't over-invest there. Clinical knowledge sections covering lesion identification and treatment protocols carry much more weight. Make sure you can identify primary vs secondary lesions and know the ABCDE melanoma criteria inside out.

Pharmacology is probably 20-25% of the exam. Retinoids and teratogenicity warnings, biologics used in psoriasis (TNF inhibitors, IL-17 and IL-23 inhibitors), and topical corticosteroid potency classes are the highest yield. Know the iPLEDGE requirements for isotretinoin cold — I had three questions on that specifically.

Infection control and HIPAA basics showed up more than I anticipated — probably five or six questions. Coming from a medical assistant background you probably have that covered, but worth a quick review in your last week so it doesn't catch you off guard.

I just passed last month so I can actually help here. The 75% passing score is accurate, that's what I've heard consistently and it matched what I needed. For chapters, don't waste too much time on the basic anatomy stuff early on — focus hard on inflammatory conditions and treatment protocols because those showed up constantly for me. Honestly the procedural knowledge section wasn't as heavy as I expected.

The one thing that made the biggest difference was doing practice questions in timed blocks rather than just reading. After week six I switched to 30-question timed sets and it completely changed how I processed the material. You start to recognize how they phrase answers and it's way less about memorizing and more about clinical reasoning. Good luck, it's totally passable with your timeline.

I've been doing the same thing, and honestly the biggest shift for me was stopping to figure out why a wrong answer was wrong instead of just moving on. Like, if you pick A and the answer is C, don't just note it and flip to the next one. Ask yourself what made A seem right, and then you'll stop falling for that trap on similar questions. It slows you down at first but it's so worth it.

For chapters, I'd weight anything related to conditions and treatments the heaviest. I did a ton of reps with a cdt common skin conditions treatment practice test and it caught gaps I didn't even know I had. The pharmacology stuff wasn't as brutal as I expected once I understood mechanisms instead of just memorizing drug names. Ten weeks is plenty if you're consistent.

I passed CDT a few months ago while working full-time and honestly the schedule thing was my biggest challenge too. I'd do 20-30 minutes on my lunch break and then maybe another 30 at night when the kids were asleep. It's not glamorous but it works. For chapters I'd say don't sleep on allergy and patch testing — I almost skipped it thinking it was niche but it showed up more than I expected. I used cdt/questions/allergy testing patch testing 2 pretty heavily in my last two weeks and it helped a lot with the clinical application questions.

On passing score, 75% is what I've heard too and it lined up with what I aimed for in practice. Wound care and skin cancer recognition are the two areas I'd prioritize if you're short on time. Pharmacology felt lighter than I expected. You've got 10 weeks which is more than enough — just stay consistent and don't cram everything into the last few days.

I failed my first attempt and honestly it stung because I thought I'd studied enough. What I didn't realize was that I'd been spending way too much time on topics I already knew from working in a derm office and barely touching the stuff that actually showed up heavily on the test. Wound infections, wound care protocols, and pre/post procedure patient education were all over it. I wasn't ready for how much clinical judgment stuff there was versus pure memorization.

Second time I passed. What changed was I stopped treating every chapter equally and just hammered the areas where I knew I was weak, especially anything around infection control and patient safety. The 75% passing mark is real, so you've got some room but not much. Ten weeks is enough time if you're honest with yourself about where your gaps actually are instead of reviewing what's comfortable. Do practice questions early, not just at the end, because they'll show you fast what you think you know versus what you actually know.
