如果您正在寻找最佳的免费行为准备，您就在正确的地方！与生活中的许多事情一样，the Internet can be a black holeof test prep resources and ACT study sites are no exception. There are some good resources, some not so good, some free and some exorbitantly priced. Lucky for you, we did the hard work of researching for you!
以下是2021年的15个最佳免费行动预备网站，应用程序和在线资源。
Free Websites and Apps
1. Official ACT Website
这official ACT website,Actstudent.org.，不仅仅是一种照顾行为物流的地方，例如注册测试并获得得分。如果您知道在哪里看，还有一定的有价值的测试准备材料。这包括样本问题，样本学生散文，大学入学计划建议，是的，是的，a full-length ACT practice test PDF由不再使用的真正行为问题组成。
Navigating the official ACT website is a bit confusing since there are so many resources, so check out our detailed post on官方法案网站的哪些部分对考试者最有帮助。
2. Old Official ACT Practice Tests
全年，该法案发布了5项额外的实践测试，由真正的行为问题组成。虽然您无法在网站上找到先前发布的测试的档案，但为您提供幸运，我们在下面提供了它们！

ACT 2008-2009实践测试
行为2011-2012 Practice Test
行为2014-2015 Practice Test

Although the tests released between 2005 and 2015 have outdated essays that you shouldn’t practice with (该法案于2016年修改了他们的论文）那these tests are still pretty valuable because the question types and overall ACT format have not changed much over the years.

Although Best ACT Prep is no longer releasing new videos, its56个视频的集合is considered the best online ACT prep by many students (at least judging by the comments).

10.麦格劳 - 山行动中心
这McGraw-Hill ACT Center是一个类似于动作学院的在线门户，包含视频课程，测验和四个全长练习测试。关于McGraw Hill的一件事是他们的行为的内容差异很大。虽然他们的科学部分非常接近真实的东西，但其他部分的问题范围从太容易太困难（你可以了解更多关于我们对McGraw-Hill资源的更多信息best ACT prep books）。
而麦格劳-希尔中心是一个伟大的resour行动ce for free ACT prep, we recommend using practice tests from places like McGraw Hill and BWS Education Consulting after you’ve exhausted other options.
11. Khan Academy
You might be thinking, isn’tKhan Academyfor the SAT? Well, true, they’ve partnered with the College Board for SAT prep, so using Khan Academy for ACT prep might not seem intuitive. BUT its math review lessons can bereally如果已经有一段时间了，因为你已经在学校学习了一个特定的话题，或者如果你在数学课上学到的时候你从来没有真正理解它。
You can use此行为数学主题清单to figure out what topics are tested on the ACT, and then search Khan Academy for lessons on the ones you need to brush up on. A lot of our students also report that Khan is a good place to start out and then take a deeper dive withmagoosh法制准备。

12.几乎有趣
Like Khan Academy,几乎有趣doesn’t have resources for ACT Prep (yet!), but both their general math lessons and SAT lessons and practice questions (of which there are around 400) are completely free and can benefit students looking to improve upon foundational skills needed for the ACT, such as reading closely, sentence structure, and linear inequalities.
这ir mission is to provide culturally-relevant test prep and their questions and lessons are replete with pop culture references (any Black Panther fans?), humor, and casual language. So if you find that even Khan Academy is too dry for you, you should definitely check out Almost Fun on either their网站or下载他们的iOS应用程序。（Remember to refer to our list of行为math topics确保您正在学习在该法案上测试的概念）。

13. Online Timed Reading Practice
可以说是你可以为行动阅读部分开发的最重要的技能是掠夺段落，因为它建议你不花钱阅读和标记段落3分钟以上。
For that reason, we dug up the following online resources to bring your skimming skills up to speed (pun absolutely intended):
14. GrammarBytes
Just as Khan Academy is a great resource for math review,GrammarBytes是对ACT英语考试的语法评论的伟大资源。它提供了几个资源，如视频，练习问题和daily Twitter tips那to help you review the topics you might be rusty on and does so in a pretty fun and interactive way.
