CAT exam study timeline - how long did it actually take you to feel ready?

I'm planning to sit the Certified Accounting Technician exam in about 10 weeks and trying to figure out if that's realistic. I have 4 years of accounts payable experience but no formal accounting credentials. I'm studying around 90 minutes a day on weekdays and 3 hours on Saturdays. Is that enough or am I setting myself up to fail?

The pass rate is something I can't find a straight answer on. I've seen people say it's around 50-60% on first attempt, which surprised me. If those numbers are right, I need to take this a lot more seriously than I have been the past two weeks.

My biggest gaps are cost accounting and financial statements. Double-entry bookkeeping I can do in my sleep, but the moment questions get into variance analysis or interpreting income statements under different frameworks, I slow down. I'm getting about 65% on practice modules and don't know if that's a decent benchmark or if the actual exam is harder.

What did your study schedule look like? Did you use anything beyond the official study texts? Those guides are dense and dry and I fall asleep halfway through the cost accounting chapters almost every time.
