# HVAC Exam Practice Prep Pass vs Structural Engineering Suite

HVAC Exam Practice Prep Pass and Structural Engineering Suite are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. HVAC Exam Practice Prep Pass sells 4 in-app purchases, starting at $3.99 per 7 days and Structural Engineering Suite sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
