# Series 66 Practice Test Prep vs SIE Exam

The clearest difference is rating: SIE Exam at 4.5 against Series 66 Practice Test Prep's 3.0. SIE Exam also leads on ratings volume (304 vs 3). Series 66 Practice Test Prep's advantage is review sentiment (50% vs 30%) and iOS requirement (9.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Series 66 Practice Test Prep sells 1 one-off in-app purchase and SIE Exam sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

SIE Exam holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: SIE Exam has 304 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Series 66 Practice Test Prep's written reviews are positive against 30% of SIE Exam's, so the app with the better star average is not the one people write more warmly about.
