Its reputation for difficulty is real but manageable — candidates who practice consistently with quality materials routinely walk in well prepared.

- Security and Administration (15-20%)
- Expression Language and Logic (20-25%)

The ACD201 exam is demanding, but its difficulty is specific, not mysterious: unfamiliar question formats, time pressure, and a few heavily weighted domains. All three respond to the same remedy — repeated, timed exposure to exam-style questions. That is what the Appian Senior Developer practice materials at RealVCE provide, and the free demo lets you measure the real difficulty yourself before committing, which is usually the moment the fear starts shrinking.
The ACD201 exam consists of 60 questions with a time allowance of 120 minutes minutes. Practicing full sets under a similar time cap is the most direct way to make sure pacing never costs you points on exam day.
Because seeing beats guessing.

If you are unsure whether the materials match your level or your study style, the demo answers that question with evidence rather than marketing, and every demo on the site is free of charge.
The passing score is 65% and the exam fee is $150 USD. Knowing both numbers early helps you plan: aim to be consistently above the passing mark in timed practice sessions before you spend the fee on a booking.
