Why I Recommend OnePrep.xyz to My Tutoring Students
As someone who specializes in test prep for high-achieving students, I actively recommend OnePrep to everyone I tutor. It’s ideal for independent practice between sessions and helps reinforce the strategies we work on.
Here’s what makes it especially effective:
🎯 1. Free Digital SAT Practice Questions from the College Board
OnePrep includes over 12,000 SAT questions, including full coverage from the SAT Suite Question Bank. These are real, retired test questions—the gold standard for prep.
Students can:
Filter by topic (like algebra, punctuation, or reading comprehension)
Drill specific question types (e.g. main idea, linear equations, transitions)
Review explanations and stats for each attempt
🧪 2. Practice in Real Digital SAT Format
The platform uses a Bluebook-style interface so students get used to the actual testing format. Each section includes:
A built-in Desmos calculator for Math
Scratch paper simulation
Timed modules
“Mark for Review” and cross-out tools
Progress tracking by question and module
📊 3. Smart Progress Tracking and Review
OnePrep automatically keeps track of:
Which questions you’ve answered or skipped
Questions marked for review
Your accuracy by topic
Total progress across all test sets
This lets students—and their tutors—see exactly where to focus next.
📈 See your progress
💬 4. Recommended by Real Students and Tutors
OnePrep is gaining traction in SAT prep communities online and among educators. Students consistently say it’s:
Easy to use
Better than expected for a free tool
Especially helpful for last-minute review
Seriously, I had a student who just started using it for the first time today and was OBSESSED with the fact that it was just like the testing platform and had all of the tools she needed—the calculator, the equation sheet, etc.
Plus, they do a really good job at staying up-to-date with the newly released questions from CollegeBoard and keeping track of questions by release date. So, if a student has mastered all the previously released questions, they can just select the newly released questions on OnePrep and practice those!
