Applying to College

  1. What is the difference between ACT & SAT?


    The SAT is a reasoning based test that is designed to measure critical thinking and problem solving abilities, while the ACT test is an achievement based test, designed to measure mastery of high school curriculum. As these tests play to two different strengths, many students find that they score higher in one format than the other; it is wise to determine which test is better suited to you. Here is a list of the most significant differences:

    *The SAT is a 180 minute test when taken without the optional 50 minute essay. The ACT is 175 minutes in length when taken without the optional 40 minute essay.

    *Both SAT and ACT contain four sections, but the sections are broken down differently. The SAT sections are Reading, Writing and Language, Math (no calculator allowed) and Math (calculator allowed). The ACT sections are English, Math (calculator allowed), Reading and Science. 

    *All questions on the ACT are multiple choice format, while SAT Math sections contain some student produced responses in addition to multiple choice questions.

    *SAT testers may be required to take an additional 20 minute section which contains experimental questions. It is unclear whether any of the questions in that section are factored in to student scores. ACT tests new questions within the body of the test.

    *SAT Reading focuses on evidence based, analytical questions, and the ACT centers more on comprehension questions.

    *The Math sections on both test cover Algebra I and II, Geometry, Trigonometry, and Probability/Statistics. The ACT appears to contain more Geometry than the SAT.

    *The SAT provides two scaled scores based on students' raw scores in the Reading/Writing and Math sections. The scaled score range is 200-800 in each of the two areas, resulting in a combined score between 400 and 1600. The ACT provides four scaled scores, each on a 1-36 scale. These four numbers are averaged to create the composite score. Both tests give numerous breakdown scores and a separate score for the optional essays, but the most important numbers from the college admissions perspective are the scaled scores presented here.

    *Neither test has a guessing penalty. Students are given credit for correct answers with no deduction for errors. It is beneficial to always answer every question in either format.


  2. What does "Super Scoring" mean?

    Some schools will take a student’s highest SATor ACT score in each section from varying test dates and combine them to calculate what is known as a  “Super Score” or composite score. Students who take the SAT or ACT more than once will be able to benefit from this means of scoring. 

  3. How many private sessions do I need to take the place of a course?

    The answer to this question is different for every student. Typically, in private sessions, the strategies can be covered and practice can be completed and reviewed in eight one-and-a-half hour sessions. However, if a student is choosing private instruction because they struggle with the test, more significant practice and review might be necessary.

  4. Do we have a score guarantee?

    Allowing for the differences in students’ abilities and efforts, GBO does not set a specific score guarantee. However, we do pledge to evaluate each student’s individual situation, and help him or her to achieve a personal best.

Cancellation Policy/ Missed Class Policy

  1. What is the cancellation policy for one on one students?

    Since our teachers set their schedules well in advance, we require a minimum of 8 hours notice to cancel a private session. Less than 8 hour notice will require a charge of one half of the rate of the appointment.


  2. What is the missed class policy for courses?

    If a student cannot make a group session such as an SAT, ACT or HSPT class, we do our best to provide an opportunity for the student to make up a missed session with another group.  Please contact us in advance to make these arrangements.
