How long does it realistically take to study for the LEC?

Really helpful breakdown, thanks for sharing. I'm at week 4 of my LEC prep and the exam prep section is exactly where I'm struggling too. Going to try the approach you described and see if it moves my scores.

Late to this thread but wanted to add — the practice test section trips up more people than any other part. If you're scoring below 72% there in practice, treat it as your only focus for at least a week before moving on. Breadth at the expense of depth in that area is a common mistake.

Good thread. One thing I'd add: don't try to cram the night before. I did 3 hours the night before my LEC and I think it hurt more than helped. Your brain needs consolidation time. Light review or full rest is better.

Congrats on passing! Can I ask — how many questions did the actual exam have compared to what the practice tests simulate? I've seen different numbers online and want to calibrate my timing during practice.

Just passed mine last month, also working full time. Honestly? 10 weeks was enough for me, but I wasted the first three just reading the rulebook cover to cover like it was a novel. What actually moved the needle was drilling questions until I could explain why the wrong answers were wrong, not just recognize the right one. I'd do a set of free lec locomotive operation and control questions every evening after work, maybe 30-40 minutes, and that consistency beat any weekend cram session I tried.

With your background you're probably fine on the 8-10 week end if you're consistent. Don't skip the operation and control stuff even if it feels intuitive — that's where I almost got caught. The test isn't trying to trick you but it's specific in ways that'll surprise you if you've only been skimming.

Honestly I almost bailed after week three. I'd been doing practice questions every night after work and felt like nothing was sticking, so I took a week off and came back slower. That ended up being the right call. I focused hard on the stuff that felt weakest -- for me that was brakes, so I drilled with a lec brake systems safety set until I stopped second-guessing myself on those questions. Took me about 11 weeks total working maybe 5-6 hours a week.

If you're coming in with related background you're probably not looking at 15 weeks, but don't let anyone tell you 6 is realistic if you're also working full time. Give yourself buffer. The people who cram and burn out aren't passing on the first try.

Honestly, I'd budget at least 10 weeks if you're working full time. I failed my first attempt after only 6 weeks of prep and I really wasn't ready — I thought I knew the material but the test goes way deeper into specifics than I expected. What killed me was the technical systems stuff. Second time I actually drilled the weak areas properly, spent a lot of time on things like lec brake systems safety because those questions kept tripping me up.

The biggest change I made was switching from just reading to doing timed practice questions every single session. It's uncomfortable but it shows you exactly where you're guessing versus where you actually know something. Give yourself more time than you think you need. You can always move the test up if you're crushing practice exams, but you don't want to rush it and have to pay to retake like I did.

I just passed last month, and honestly the timeline varies a lot but I'd say 8 weeks was the sweet spot for me with a similar work schedule. The thing that actually moved the needle wasn't grinding more hours — it was drilling by system instead of just doing random questions. Once I focused a section at a time, like really locking in lec brake systems safety before moving on, stuff started clicking way faster.

You've got the background which helps, but don't skip the systems you feel "pretty good" about. That's where I lost points early on. Six weeks is doable if you're consistent, but if you can swing 8-10 you'll go in feeling a lot less stressed.
