Pre-Algebra Tutor • +25 Subjects

I'm Scotty! I am currently a senior at Harvard College pursuing a Bachelor's degree in Sociology with a secondary (minor) in Theater, Dance, and Media. I know full well that struggling with course material is tricky to navigate; I have not always felt comfortable going straight to the professor or teacher to ask for help. That's why I love tutoring - I aim to be a helpful resource for students, blending the toughness of a coach with the warmth and comfort of a friend to provide the best atmosphere for those I tutor. Hobbies: art, books, dancing, reading, music, writing, singing

I'm currently a Junior at the University of Pennsylvania majoring in Politics, Philosophy, and Economics and a 2014 graduate of Phillips Academy.

I have lots of experience in mentoring students individually and teaching in the classroom through being a student intern for a sophomore honors English class. I love working with students who are preparing for tests or college admissions because it gives me an opportunity to impart my knowledge of the college application process to others and empathize with them on all their concerns. I believe that education and critical thinking are key to expanding your horizons and achieving your goals in life. Hobbies: reading, writing, books, music, art

Allan

12th Grade math Tutor • +85 Subjects

I'm a big Boston Celtics fan and I speak three languages. I can get you the test results you need to succeed because I went through the exams myself and performed well. The first time I took the SAT I actually wasn't satisfied with my score, so I spent 2 months working hard to get my score to where I wanted it to be. The second time I took the exam I saw a 200-point increase. Previously, I have had experience teaching the SSAT and the SAT. The student I tutored in SSAT successfully passed the exam is now attending a private high school abroad. With VarsityTutor's online learning platform, I will be able to transfer knowledge in a visual, easy-to-understand manner. I look forward to being your tutor and helping you reach your academic goals. :)

I am eager to help students thrive because I'm still very much a student myself, and will be for the foreseeable future. Though I enjoyed my time as an undergraduate student in Literature, and learned quite a bit during my time at Vanderbilt, there's still more work to be done. I am working towards a Master's degree, and will continue on from there.

I am especially committed to supporting first-generation college students, those for whom English is a second language, and working adults as they navigate the challenges of higher ed. Nevertheless, I have taught and mentored graduate students at Harvard and talented undergrads in a variety of disciplines and welcome helping with theses. In addition to teaching, I have a background in publishing and editing, and have been a writer since childhood. Language creates reality, and interpreting and using it well opens many doors. I delight to see students realize their capacities and expand their universe. Hobbies: reading, writing, books, music, art, travel

Frequently Asked Questions

Students commonly struggle with sentence structure issues like comma splices, run-on sentences, and fragments—often because they understand the concept but apply it inconsistently in their own writing. Other frequent challenges include pronoun-antecedent agreement, verb tense consistency (especially when writing narratives), misplaced modifiers, and understanding the difference between restrictive and non-restrictive clauses. Tutors can diagnose exactly where your writing breaks down and provide targeted practice on those specific patterns rather than reviewing grammar rules you already know.

Strong grammar tutoring goes beyond correcting errors—it teaches you to recognize patterns in your own writing and edit strategically. A tutor can help you understand that grammar serves your writing voice and clarity, not the other way around. They'll work with you on drafting, organization, and argument development first, then focus on mechanics and style in revision, so you're not getting bogged down in comma rules while still forming your ideas.

Grammar rules are non-negotiable standards (subject-verb agreement, proper comma usage), while style choices are intentional decisions that reflect your voice—like using short sentences for emphasis or starting a sentence with "And." Understanding this distinction helps you break rules deliberately for effect rather than by accident. A tutor can teach you which errors undermine credibility and which stylistic choices strengthen your writing, so you're making conscious decisions instead of guessing.

Clear grammar makes your arguments easier to follow—a misplaced modifier or unclear pronoun reference can confuse your reader about what you're actually arguing. Strong mechanics also build credibility with teachers and standardized test graders, who expect polished writing. Beyond correctness, understanding sentence variety and structure lets you emphasize key points, control pacing, and guide readers through complex ideas more effectively than repetitive, simple sentences.

Grammar checkers flag errors but don't explain why they're errors or help you understand the pattern in your writing. A tutor reviews your actual writing, identifies recurring mistakes (like consistently misplacing commas in introductory clauses), and teaches you the underlying rule so you can catch similar errors yourself. They can also distinguish between what's actually wrong and what's a stylistic choice, which automated tools often can't do.

Tests like the SAT and ACT have specific grammar and writing sections that reward understanding conventions and sentence construction, not just avoiding errors. Tutors can teach you to recognize common test patterns—like identifying the most concise way to express an idea or spotting misplaced modifiers in multiple-choice questions. They'll also help you apply these skills under timed conditions, so you're not just knowing the rules but applying them quickly and confidently.

Grammar tutoring benefits writers at every level. Struggling writers need foundational support with sentence structure and basic conventions, while advanced writers often want to refine their style, understand nuanced punctuation choices, or master complex sentence construction for academic writing. A tutor can meet you where you are—whether you're building confidence with basics or polishing advanced writing for college applications and essays.

Effective revision isn't just rereading—tutors teach you specific techniques like reading aloud to catch awkward phrasing, reading backward to spot fragments, or focusing on one type of error at a time rather than trying to fix everything simultaneously. They'll also help you develop a personal editing checklist based on your most common mistakes, so you're not spending time looking for errors you don't typically make. These strategies make revision faster and more efficient than hoping you'll catch everything on your own.
