FLS exam — how to split prep time between skills lab and the written portion
I'm a surgery resident prepping for the FLS and trying to figure out how to split my limited time between the manual skills portion and the cognitive exam. I have about 8 weeks before my scheduled date and can realistically get in 45 minutes per day on the skills box and another 30-45 minutes on knowledge review. Is that enough, or am I setting myself up to fail the skills section specifically?
The cognitive test feels manageable — I've been scoring around 75-80% on practice questions covering laparoscopic principles, energy sources, and patient positioning. The skills portion is a different story. My peg transfer time is around 95 seconds and I need it under 60 to score well. The precision cutting task is even messier — I'm too slow and losing points on dropped pieces.
My program director says most residents who fail do so on skills, not the written, so I'm trying to shift my ratio toward box training. But I'm nervous that 45 minutes per day isn't sufficient for the coordination improvements I need in 8 weeks. Does motor learning actually work on that timeline, or do I need to find more time somewhere?
For those who've passed — what did your skills box practice actually look like day-to-day? And did you use the official FLS kit or a generic trainer?
Daily short sessions beat weekly long ones for motor learning. I did 30 minutes every single day for 10 weeks and brought my peg transfer from 110 seconds down to 48. Consistency matters more than volume on any given day.
Get the official FLS kit if you can — the peg dimensions and instrument resistance are calibrated to match exam day. Generic trainers can build slightly off habits.
The cognitive portion is straightforward if you've done your basic surgery training. Focus 80% of your remaining time on the box. Your scores show you don't need more written review right now.
I failed my first attempt because I spent 70% of prep on the cognitive exam, which I was already passing, and not enough on precision cutting. If your written scores are 75%+, redirect that time to the box immediately.
The endoloop and intracorporeal suturing tasks have the steepest learning curves and also the highest point values. If you're 8 weeks out, prioritize those over peg transfer even though peg transfer feels easier to improve quickly.
My co-resident practiced suturing 20 minutes every morning before rounds and went from failing to 89th percentile in 7 weeks.
Just passed mine about six weeks ago so this is fresh. Honestly the thing that changed everything for me was treating the skills lab time as pure muscle memory work and nothing else -- I stopped trying to "understand" the tasks during box time and just did them over and over. The written portion is actually more manageable than people think if you spend your knowledge review time on the right stuff. Focus hard on the laparoscopic fundamentals, trocar placement, energy sources, and complication recognition. Those topics carry a disproportionate chunk of the questions.
For your 8 weeks I'd flip the ratio toward skills for the first four weeks since that's what most people underestimate. It takes longer than you think to get intracorporeal suturing to feel automatic. Then in the back half shift more time to the cognitive side. One thing I didn't expect -- timed practice matters a lot for the skills component, so don't just practice the tasks, practice them against a clock. That stress exposure before the real test day is worth more than extra raw repetitions.
I went through FLS prep last year and honestly the cognitive portion clicked for me once I stopped trying to memorize answer keys and started picking apart why the wrong choices were wrong. Like for fls extracorporeal suturing questions, if you understand the tissue tension principle behind why you'd fail a throw, the distractor answers become obvious. That mental model transfers way better than flashcards.
For your split, I'd honestly lean heavier on skills box early in your 8 weeks since muscle memory takes longer to build than knowledge. Your 45 minutes there is well spent. But don't let the cognitive stuff slide -- even 30 minutes of active review where you're writing out why each wrong answer fails you will compound fast. By week 5 or 6 you can shift more time toward written as your hands get consistent.
Quick update on my end -- I'm about 5 weeks in and just scored a 78 on the written practice test on the SAGES study portal, which honestly surprised me because I felt way less confident going in. The cognitive material clicked faster than I expected once I stopped trying to memorize everything and just focused on the actual decision-making logic behind each skill.
I'm sitting the real exam in 11 days. My skills times have gotten a lot cleaner but the intracorporeal knot tying still isn't where I want it. If you're still early in your 8 weeks I'd say don't neglect the written portion thinking it's the easy part -- it takes more time than it looks.
