Failed MOS Excel twice — what am I missing in my prep? — Forums

I just got my second failed attempt at the MOS Excel Expert exam and I'm honestly pretty demoralized. Both times I've scored around 680, and you need 700 to pass. I've been using a MOS practice test from a couple different sites but I keep getting tripped up on the same stuff — advanced formulas, specifically the nested IFs and some of the data validation tasks where you have to configure specific error messages.

My study routine has been maybe 2-3 hours a week for about six weeks, which in hindsight probably wasn't enough. I found a solid MOS study guide on Reddit that covers all the objective domains, but I feel like reading about it and actually doing the timed tasks in the real exam are totally different animals. The live-in-application format really throws me off.

Has anyone else struggled with the hands-on task format? I'm thinking I need to shift from reading to just doing practice tasks constantly. Any exam tips on how you structured your last few weeks before passing would be huge.

Don't underestimate the data validation questions — they're worth more than they look. I flagged every task I wasn't 100% sure on and came back at the end. That alone probably saved my score. You're close, don't quit now.

The jump from 680 to 700 is real but it's doable. I was in the exact same spot last year. What finally worked for me was ditching passive study entirely — I spent my last two weeks just doing timed practice tasks back to back, no notes. Muscle memory is everything on this exam. Also, make sure you know keyboard shortcuts cold; they save so much time when the clock is running.

Honestly the hands-on format is what makes MOS harder than people expect. I passed on my third attempt, and the thing that clicked was learning to read the task instructions twice before touching anything. Sounds obvious but I kept rushing and misreading what they actually wanted. For nested IFs specifically, just build a few from scratch every single day until it feels automatic. Two weeks of that and I stopped second-guessing myself.
