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

Late to this thread but wanted to add — the crecy battle section trips up more people than any other part. If you're scoring below 75% 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 CRECI and I think it hurt more than helped. Your brain needs consolidation time. Light review or full rest is better.

This is exactly the thread I needed. I sit for my CRECI in 2 weeks and have been second-guessing my prep. The crecia area you mentioned is definitely my weak spot. Thanks for the honest breakdown.

For the people asking about study timelines: I studied 74 minutes per day for 14 weeks working full time. It's absolutely doable without burning out. The key is consistency — missing days hurts more than extending your timeline.

Honestly, it took me about 10 weeks studying maybe 6-8 hours a week, which sounds like a lot but I just carved out an hour on weekday mornings before work and then a longer block on Sunday. I work close to your hours and I was really worried I'd burn out, but breaking it into small daily sessions made it way more manageable than I expected. The first couple weeks I wasn't even sure I'd make it through all the material.

The hardest part for me wasn't the volume, it was staying consistent when work got crazy. Some weeks I only got in 4 hours and I had to accept that and just pick back up. If your background is related you're probably in decent shape -- I'd say give yourself 8-10 weeks to be safe rather than rushing it. You don't want to sit for it feeling unprepared, that's just wasted money and stress.

I'm in a similar boat — work full time and studied for about 10 weeks before I felt ready. Honestly the timeline matters less than how you study. Early on I was just marking the right answer and moving on, and my scores barely budged. What actually moved the needle was stopping to understand why the wrong answers were wrong, not just why the right one was right. That shift alone probably saved me weeks of spinning my wheels.

With 47 hours a week at work, I'd plan for 10 to 12 weeks but don't stress if you need the full 14. Give yourself 3 to 4 solid sessions a week, and when you miss a question, dig into it. It's slower at first but you stop seeing the same mistakes twice. That's when it starts clicking.
