# 三类人员题库 vs 千源题库

The clearest difference is iOS requirement: 千源题库 at 10.0 against 三类人员题库's 12.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 三类人员题库 sells 10 one-off in-app purchases and 千源题库 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
