Our Math Tutoring Approach
A structured, three-phase method that turns confusion into confidence.
1. Diagnose Gaps
We begin with a diagnostic assessment to pinpoint exactly which foundational concepts are missing or weak. Many students struggle with advanced material because of overlooked gaps in earlier topics. Identifying these gaps is the fastest route to improvement.
2. Build Foundations
Once gaps are identified, we rebuild understanding from the ground up using clear explanations, step-by-step worked examples, and targeted practice problems. Students develop true comprehension, not just memorized procedures.
3. Apply to Tests
With a solid foundation in place, we shift to applying knowledge under test conditions. Students learn time management, question prioritization, and the specific strategies that lead to higher scores on school exams and standardized tests.
Students We Work With
Our math tutoring serves students at every stage of their academic journey.
Middle School Students
Building a strong foundation in pre-algebra, fractions, decimals, and basic geometry. Early intervention prevents gaps from compounding in later years.
High School Students
Support for Algebra I and II, Geometry, Trigonometry, Pre-Calculus, AP Precalculus, AP Calculus, AP Statistics and the math Regents (AP & Regents tutoring). We help with homework, exam prep, and maintaining a strong GPA.
College Students
Assistance with college-level calculus, linear algebra, statistics, and discrete mathematics. Particularly helpful for students in STEM programs who need to solidify their quantitative skills.
What Our Math Students Say
“Dr Donnelly was professional, knowledgeable, and pleasant to work with when our son needed to get started on working for his AP Calc BC, which his school did not offer. All went well and he got into Oxford, so we're grateful for Dr Donnelly's guidance!”
“Dr. Donnelly's way of teaching is very calm and effective. By teaching math in the simplest ways possible he managed to make it interesting and challenging at the same time. I am happy to report that I recently passed my TASC exam with a score of 90 percent.”
Math Tutoring — Frequently Asked Questions
Dr. Donnelly tutors all levels from pre-algebra and middle school math through AP Calculus AB/BC, college-level statistics, and standardized test math sections including SAT, ACT, GRE, and GMAT quantitative reasoning.
Each session begins with a targeted review of concepts the student is struggling with, followed by guided problem-solving and independent practice. We use diagnostic assessments to identify gaps and build a customized learning plan that evolves as the student progresses.
Yes. Online math tutoring sessions are conducted via Zoom with a shared digital whiteboard, making them just as effective as in-person lessons. Many of our students across the country work with Dr. Donnelly exclusively online and see the same excellent results.
Many students start to notice improvement within the first several sessions, but there is no fixed timeline. The pace depends on the starting level, the nature of the gaps, and the frequency of sessions. Regular weekly sessions combined with practice between lessons give students the best chance of steady improvement in their grades.
Absolutely. Dr. Donnelly integrates standardized test strategy into math tutoring, covering the specific question types, time management techniques, and content areas tested on the SAT, ACT, GRE, and GMAT. Many students combine academic math tutoring with test prep for maximum results.
