# USMLE Surgery PreTest vs Case Files Surgery

The clearest difference is review sentiment: USMLE Surgery PreTest at 80% against Case Files Surgery's 50%. USMLE Surgery PreTest also leads on update cadence (fortnightly vs every 17 months) and ratings volume (38 vs 1). Case Files Surgery's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. USMLE Surgery PreTest sells 2 in-app purchases, starting at $15.99 per month and Case Files Surgery sells 8 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Case Files Surgery holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: USMLE Surgery PreTest has 38 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of USMLE Surgery PreTest's written reviews are positive against 50% of Case Files Surgery's, so the app with the better star average is not the one people write more warmly about.

USMLE Surgery PreTest ships an update fortnightly, Case Files Surgery every 17 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
