Provides Useful Tactics
Testking's Act practice test online is by far the best tool for ACT preparation. It teaches very useful tactics and presents a complete vocabulary list, which provides 99% of the hard words in ACT tests. I bought this for my daughter who is preparing to take the SAT.

They are rocking .I will buy them again.

It Highlights Important Strategies
I loved the Act test practice online by Testking. It should be the main ACT prep method that anyone uses, which is a great source of short reviews and real ACTtests. Testking is the best I've found out there, and is much better than others.The strategies highlighted section wise, proved to be an invaluable source of information.Specially The maths review is definitely solid. It goes over all the maths concepts you need to know, and then gives plenty of practice questions. All credit goes to Testking.

Easy Language
Online ACT practice tests provided by Testking were very helpful. They're a bit harder than the real test, but they'll still prepare you very well. I took sections of each of these tests after I read the corresponding section review, and I found that my score improved a lot! The best part of is how conversational and easy to understand the language is. The language made it easy for me to read and to learn. Testking's team is doing great work in helping students.

No Complaint
I worked as a 'coach and when my daughter needed to review for the ACT.Testking's Act practice test online was the first one I thought of. I'm pleased to see that they maintain a slightly reverent approach to the ACT, that makes it more interesting for the reader. My daughter read it without complaint, and even once said, "Its great", which is high praise indeed for a test prep book. As for the results - well, we're still waiting for the test scores. But my daughter said the test was 'easy' which I hope is a good sign.
