About Sebastian
Hi, I’m Sebastian — a senior at the University of Florida studying finance. I’ve helped 200+ students in 4+ years, all online. I scored a 1540 SAT (780 Math / 760 Reading & Writing) and a 34 ACT.
I wasn’t a 1500 scorer from day one — I started in the 1200s. What changed for me was getting consistent and learning how the test works — patterns, traps, and timing.
Students tend to connect well with me because I’m young and took the SAT/ACT not long ago. I know what the current test feels like and how to prep without it taking over your whole week.
I work with students across a wide range of starting scores (900s–1400s) and different schedules. Many students see 100+ point gains when they stay consistent (sometimes 200+).
Message me your current score + test date + weakest section (Math or Reading & Writing), and I’ll tell you what I’d focus on first.

Perfect! Sebastian has been following the official list of math subject matters required by the SAT with our son successfully. Our son is understanding subjects better and faster so we are hopeful on a good score. Our son says tutoring is clear, and very easy to understand. Also, Sebastian accomodated to our son’s crazy soccer schedule so that was a plus.
Recommending him 100%!!- Maru's son Benjamin was a pleasure to teach in our 1-1 program. He was incredibly attentive and made sure to properly understand the material by asking great questions! This led to him increasing his score by over 150 points!Sebastian's response :

Sebastian made SAT prep very simple. He explains concepts clearly and keeps me very focused in our sessions. I highly recommend his services.
Sebastian has a very good tutoring style and really helped me learn and understand the material for my exam. I feel very confident going into my upcoming SAT exam and highly recommend his services!
Sebastian really cares about how his students are doing and puts in a lot of work to make sure everyone succeeds. After only one month of tutoring he was able to help me boost my score by almost 200 points. His tutoring sessions really help you grasp all the concepts you may be struggling with and even if you don’t understand at first, he takes the time to explain it until you get it.
Sebastian is an exceptional tutor in all areas of standardized prep. He really helped me improve in my weaker areas especially in truly understanding the material specific to the exams. He also makes the class intriguing and keeps me attentive the entire time and helped me develop a better drive to study.
Sebastian has done a great job with the tutoring! Before taking his classes I got a score of 980 and after I ended up with a score of 1110. His classes have really helped me understand how to properly take the SAT.
He is good at explaining both reading and math subjects in the SAT
Sebastian Gonzalez’s SAT program is beyond compare. Honestly I thought I didn’t need much help in reading or writing but this program proved me wrong. Not only did my reading scores increase but I also feel more confident in my writing. I would recommend to anyone because his tutoring is excellent!
Sebastian reached out to me about his tutoring when I was struggling to reach bright futures with a score of 1260. With his teaching strategies and the constant practice of the SAT, I managed to improve my reading score over 100 points and my math score 90 points. I ended up receiving the 100% bright futures, with a score of 1460.
I think Sebastian is a trustworthy tutor because of how he makes everything simple and easy to learn and cooperate in class. He explains everything thoroughly and always gives you a chance to ask questions.
Sebastian did a great job tutoring me on the areas of the SAT that I struggled with the most. He taught me new strategies on taking the reading section, which ended up boosting my reading score by 200 points after his tutoring.
Sebastian is everything you can ask for and more. He is like an angel sent down from SAT heaven. After tutoring with Sebastian my SAT score went up almost 200 points. He is very knowledgable and makes the hardest of concepts so easy. I would reccomend Sebastian to anyone and everyone looking for a tutor. He has zero flaws in his tutoring game it is like watching Micheal Jordan play Basketball. 10/10
I was able to learn a lot from Sebabstian I was able to raise my score by about 200 points. Great teacher and would highly recommend.
Sebastian has been a friend of mine for almost all of my life. I always knew that he was very gifted when it came to math and numbers when we were in school together. However, I didn’t know that it would actually help me out. He tutored me for a couple of weeks and improved my math score from 530 to 750. I almost got a perfect score on the math thanks to my friends tutoring. It is very professional and I recommend everyone to give his tutoring a shot.
he helped me with my sat tutoring and he was a nice, well spoken guy who had a lot of patience with his students and we’ll help you if your going through a financial issue very trustworthy in my opinion
