Attento Tutoring is a Miami-based tutoring business founded by college student Sergio Attento in 2025. Attento specializes in SAT, ACT, and PSAT prep services, and uses a personalized approach to tutoring, with Sergio creating a plan for every student to reach their goal.
Current Student? Log inImagine you're training for a bodybuilding contest. You have impeccable shoulders, chest, and arm muscles, but your legs are severely lacking. Would you hit all your muscle groups at the gym equally, or would you put extra focus on your legs? Obviously, you should mainly train the area that lags behind the rest of your body.
When practicing for standardized tests, the same logic applies. A student who is already strong in grammar should not spend half their time studying grammar; instead, they should focus on the sections they falter in the most. Test prep books and online courses ignore this, using a one-size-fits-all approach to tutoring.
Attento Tutoring is different. Here, students will be required to take a short diagnostic or a valid practice test before tutoring begins. Sergio will review your results and find what areas you must target most. Then, he will assign targeted work based on that, building a plan to get you to your target score.
A clear, four-step path from "not sure where to start" to a targeted tutoring plan.
Your student completes a short, focused diagnostic online, or submits a valid, recent practice test score instead. No scheduling required to begin.
Sergio personally reviews the results: strengths, weaknesses, score gaps, and error patterns.
Sergio walks you through what the diagnostic revealed and maps out a recommended plan together.
If it's a fit, your student begins sessions built around exactly what they need to improve.
Test prep and academic fundamentals, taught with the same structured, diagnostic-first approach.
Section-by-section strategy for the Digital SAT, covering Reading and Writing, Math, timing, and pacing.
Targeted prep across English, Math, Reading, and Science, built around the ACT's tighter pacing.
Early foundation-building for underclassmen and a strong step toward National Merit consideration.
Every Attento student gets their own online dashboard to track scores, see what's due, and practice on their own time.
Set a target score, log every practice and official test, and see the trend on one chart.
Upload an SAT or PSAT score report and the portal reads it for you, breaking your results down by content domain.
Your upcoming sessions and test dates are always one click away, with reminders before each one.
Each assignment comes with Sergio's instructions and any files you need, and you turn it in right from the dashboard.
Sergio assigns question sets targeted at the areas you're working on, and you take them like a real test.

Founder & Lead Tutor, Attento Tutoring · LinkedIn
Attento Tutoring was founded on a simple idea: test prep should be strategic, not repetitive. Sergio scored a perfect 1600 on the SAT, is a National Merit Scholar, and has spent years breaking down exactly how these tests are built, where students lose points, why careless errors happen, and what separates a good score from a great one.
Students describe the approach as serious but relatable: direct about what needs work, clear about the plan to fix it, and genuinely invested in watching students improve.
No wasted sessions: every hour is built around a specific, identified gap.
Parents know exactly what's improving and what's still being worked on.
Progress is tracked against the original diagnostic, not just a feeling of "doing better."
Start with the free diagnostic at attentotutoring.com/diagnostic. It takes a short amount of time and gives Sergio the information he needs before recommending anything.
No. The diagnostic is a short online test your student completes on their own. The results review call is a separate, free conversation where Sergio walks you through those results and discusses a plan.
Yes, the initial diagnostic is always free, with no obligation to book tutoring afterward.
Both. Sergio tutors in person in the Miami area and online for students anywhere. Format is discussed on your results review call.
No tutor can honestly guarantee a specific score. What Sergio can commit to is a structured, evidence-based plan and consistent tracking of progress against your student's diagnostic results.
It depends on the diagnostic results, timeline until the test, and the student's goals. Sergio will recommend a specific frequency on your results review call, commonly once or twice a week.
Usually, yes: short, targeted practice between sessions, tied directly to what was covered, so progress compounds rather than resetting each week.
Yes. Parents get visibility into progress and performance so there are no surprises, not just a black box of weekly sessions.
Yes. Alongside SAT, ACT, and PSAT prep, Sergio offers reading and math tutoring for general academic support, which often reinforces the same fundamentals tested on standardized exams.
Not at all. The diagnostic-first approach works precisely because it meets each student where they are, whether that's building core fundamentals or fine-tuning an already-strong score.
