Multiple Approaches

We show you how to get a problem right even when you DON’T know the math!.

The PowerPrep is the ONLY course that demonstrate alternative methods for answering all questions

You learn how to apply real world logic, backsolve, plug in and compare answer choices, pick numbers, process of elimination and estimating. 

Math is cumulative

Many students fear math mainly because they say it doesn’t make sense in the real world. Even though students constantly ask why—they rarely get an answer that works for them. That’s because math is often presented without context as a series of rote rules students are told to memorize without knowing the “why”. We put math into context and explain WHY!

Have you ever watched a math teacher work a problem in class and it seems easy or obvious.  But, when you get home and try it on your own  you get totally stuck? Well, we provide exhaustive details that you control. You decide when you need  the instructors help—so you NEVER get stuck. This allows you to progress quickly and at your own pace.

Science Reasoning

We analyzed years of Science Reasoning questions and know exactly what you will face on the test.

The best way to prepare for Science Reasoning is to do lots of these. We give you over 15 specifically selected actual Science Reasoning Passages with OUR detailed explanations for hours and hours of prep on science reasoning.

It’s heavy on graphs, diagrams, and images

They test your ability to analyze the “sciency” data they give you.

What they test: Remember this is more like “Reading Comprehension” and NOT a test of your knowledge of science. The passages provide all the information you need.

The Good News: Science Reasoning is WAY more "reasoning" and far LESS "science".

But the “Sciency” jargon might be foreign for many students. Always bear in mind, this section simply tests a student’s ability to absorb the STATED/GIVEN information in a passage and “reason” with that information. Everything you need is provided—mostly (they have begun to sprinkle in a very small number of questions that test very basic science information students should have learned in high school).

We teach you ABOUT the test:
  • 7 “science” passages
  • 5-7 questions per passage
  • 35 minutes
  • Topics: biology, chemistry, physics, and earth/space science like astronomy, geology, and meteorology
We teach you the two (2) keys for answering questions. How to:
  • Find the stated data WITHIN the passage
  • Use logic and reason to EXTRAPOLATE unstated assumptions and conclusions.
  • You will learn to: Interpret, Evaluate, Reason, Solve Problems
We teach approaches and strategies for the three (3) passage types:
  • Data Representation (questions based on tables, graphs, and diagrams)
  • Research Summaries (tables and graphs with additional information and summaries about the design of the experiment)
  • Conflicting Viewpoints (several related hypotheses or views that are inconsistent with each other)

Essay Writing

The essay is not mandatory. However, writing well is critical for college success. This means having the ability to logically and clearly express your ideas.

There are two types of essay writing and we teach BOTH of them: “Argument” and “Issue” essays.

The Essay Writing class will:
  • Familiarize students with each type of essay question
  • Explain a methodology for test-day
  • Provide rubrics showing the keys for an excellent, average, and poor response
  • Develop a student’s ability to create quality opinionated essays
  • Teach essential elements that make up an effective analytical essay.
  • Provide model essays, responses, and analysis based on the rubrics
You learn how to create:
  • Strong thesis statements
  • Interesting opening paragraphs
  • Clear supporting paragraphs
  • Logical conclusions
  • Useful transitional statements
You also learn to:
  • Absorb and analyze the issue or argument
  • Develop and recognize the key points
  • Arrange your proof
  • Analyze counter arguments
  • Use assertive language
  • Evaluate your logic and grammar
We teach you to use a check list:

Parents Love Us

Barry Schnaitman says:

“My oldest daughter was able to improve her score and is now attending a high cost private college with half the tuition being covered by scholarships. We are back ordering again to prepare our other teenagers much earlier than before. Thanks!”

Eva Bowers says:

“Hurricane Katrina destroyed my oldest son’s high school forcing him to attend 3 different schools his senior year. We were worried about how all this change would affect his ACT score. After using this program, his score increased and he received a scholarship. I am now ordering the program for my other son. Thanks you so much NFL players and sponsors for making this program available.”

James Schumacher says:

“Our Family certainly thanks you all for developing and supporting this program. Last year, we got the program for our daughter and now she is going to college on a full ride scholarship. Thank-you for concern and help.”

Grace Mischenko says:

“Thank you!! My oldest got a full-tuition waiver scholarship due to his score! Now, my second is getting ready to take his tests!”

Andrea Johnson-Harvey says:

“Great product. My son has a reading disability and needed to raise his SAT scores in order to gain NCAA eligibility. Your program helped him do that, and he is now playing lacrosse in college. Thank you”

Lisa McCann says:

“Thank you for providing this opportunity to students. Though my son is only a freshman, this program has already helped my son score better on tests and has increased his confidence in test taking. That in itself is a great advantage to him.”

Christina Griffis says:

“As a former homeschooling family, two of our sons utilized Power Prep for the ACT and were successful in raising their scores. Now, as a guidance counselor at a private school, I am happy to relate that experience to the students! Because of my family’s positive results with eKnowledge, I have insured that the DVD has been available at our school for the past two years. Thank you for a software package that has been proven to help students increase their test scores! Well done! :)”

Kimberley Bates says:

“Thank you all, for the opportunity you have afforded our children throughout the last 5 years. (with your help) Our 2 eldest have gone on to Wellesley College and Sweet Briar college, with full academic scholarships. Our youngest is beginning high school in the fall. We know this program will give her a head start and help her feel comfortable taking the SAT and ACT. Thank you for your thoughtfulness and generosity.”

We are very happy for Caity. She was offered a full-ride softball scholarship to Stanford. But she needed to improve her test scores to accept the scholarship.
