Welcome to GradeAssess

GradeAssess is your partner in preparing for standardized tests. With so many prep books and resources available, we chose not to reinvent the wheel, but rather to extract the most out of those resources by providing instant and detailed analysis on practice test performance. Doing great in math but struggling with reading comprehension? With GradeAssess, you can focus on the specific areas and skills that need more work, rather than mindlessly taking one practice test after another and seeing little to no progress. Our Knowledge Branch, which breaks down all of the skills tested on each assessment, will guide you in what to study and make the most out of your limited time.

To take a standardized test in GradeAssess, simply obtain a physical book that is listed in our system (e.g. Barron’s, Kaplan, Princeton Review) and submit your answers online—like an online Scantron but much more powerful. Once you submit your answers, we’ll provide the rest and instantly get you started on your journey to achieving your academic goals. Knowledge Branches:

The following concepts below are the backbone of the ACT


A large portion of the ACT Math section will be on Algebra, which covers everything from the basics of Pre-Algebra to the more advanced topics of Algebra 2. These questions will mostly deal with different types of one- and two-variable equations and expressions, functions, polynomials, and complex numbers.


This category focuses on the topics that are typically introduced prior to variables and algebra. This includes interpreting data, number sense, numbers in relation to another, and statistics.

Graphing and Coordinate Geometry

This category relates to anything regarding graphs and coordinate planes.

Plane Geometry

This category includes everything regarding two- and three-dimensional shapes: area, perimeter, volume, angles, and more.


This category focuses on the different kinds of trigonometry problems regarding graphs, identities, and ratios.

Big Picture

This category tests whether or not students understood the main point of the passage

Development and Function

This category tests understanding of literary devices and their function in a text, as well as the function of certain phrases or paragraphs in developing the entire passage.


The genre of the text you are reading may have a significant impact on your performance based on your familiarity with the style of writing, subject, and vocabulary. So we have categorized each question into its respective genre to account for this factor.

Little Detail

In contrast to “Big Picture,” this category focuses on attention to detail and how these details contribute to the passage.

Paired Passages

For paired passages, there are two types of passages in which the types of questions are typical for each so we categorized questions based on this type.


This category focuses on vocabulary in a passage and prompts students to analyze what a word means in a certain context and why the author chose that word.

Rhetorical Skills

This category focuses on the language and delivery of the text, testing understanding of language use, developing an idea, and organizing sentences to create a cohesive statement. Students are also prompted to think about writing style to express ideas in a precise, concise, and consistent way.

Usage and Mechanics

This category covers more of the practical elements of writing, such as grammar, different classes of words (nouns, pronouns, verbs, etc.), punctuation, and sentence structure

Passage Type

The ACT Science section has three types of passages that you can expect and the types of questions are typical for each one, so you will be able to see in which passage types you tend to be weak or strong.


These are the skills that the ACT Science section tests which include application of the text to solve a problem, basic science knowledge that you must have prior to the exam, comparing and contrasting ideas, and comprehension of the passage.


The subject of the text you are reading may have a significant impact on your performance based on your familiarity with the content and terminology. So we have categorized each question into its respective genre to account for this factor.
