Great For Math Practice
I think ACT Math Practice by Testking is great for ACT math prep. It has practice tests that all seem well written. It breaks down the maths section into major topics (pre-algebra, algebra, geometry, trig, etc), then covers specific types of problems within each major topic. There are mini-tests over each category too, which I think is really helpful. I've pretty much used it to cover everything. The questions aren't quite as hard as those in the recent official ACT.

Concise And Straightforward
ACT maths section of the test is where one can improve most by studying. The questions on the practice tests mirror those from real tests.Testking's ACT Practice Math has given the explanations are far superior to those in the official guide. They are concise, straightforward and easily understood - so much so that my son wished he had this as a study guide for his maths classes. It highlights all the formulas one should know for the exam. Good luck to all test-takers using Testking.

Great Focus On Weak Areas
My daughter appeared in ACT and could not qualify it.Then my colleague suggested to get her Testking's Act practice maths.Truly it covers the concepts the ACT will test - so one can quickly discover their weak areas and focus their efforts most productively. Testking's guide has retained its value as a quick and easy maths reference.Now my daughter has got admission in college and we recommend testking to everyone we know.It is the tool to improve your maths.

Purchased At Affordable Price
I purchased Testking's practice Act maths, because maths is my weakest subject on the ACT. I was scoring a 16 on the ACT test, I need a 20 for the promised scholarship.I just read some of the tips, and nothing else and it raised my score.Not only did I use it to practice for the ACT, but I also used it to practice for the another maths test. I think its a great source of practicing your maths to remove all the defficiencies.Thanks to Testking. You are really awesome.

Thanks To Testking
I scanned through the ACT maths practice of Testking before deciding to purchase this one. I am glad I did. They provide a full range of the maths problems on the ACT test, and also provide full explanations of the answers if you come across a problem you just can't figure out. I would highly recommend Testking to anyone who is planning on taking the ACT test. I was better able to understand how to work through the problems.I am successful on ACT.Thanks again.
