雅思考试有剑1-剑15，但是在数量方面远不及托福的TPO(TOEFL Practice Online，即托福真题模考版)，这就造成雅思考试准备比托福更困难；另外托福考试题目存在规律性重复是事实，所以就有了大量的“机经”与考试预测，而雅思考试预测远不如托福的命中钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 率，从而使部分考生更倾向于考福。
IELTS test has sword 1-sword 15, but in terms of quantity, it is far less than TOEFL's TPO (TOEFL Practice) In addition, it is a fact that there are regular repetitions in the TOEFL test, so there are a lot of "opportunities" and test predictions, and the prediction of IELTS test is far less than the hit rate of TOEFL, so some candidates are more inclined to take the test.
