A 1520 SAT is a highly competitive score, and for engineering applicants, the 800 Math score is the most important part of that number. While a 720 in English is slightly lower than the median for some Ivy League schools, it will not be the reason you get rejected from a top engineering program. Top STEM schools like MIT, Caltech, and Carnegie Mellon prioritize your quantitative ability above all else. If you have a perfect math score, you have already cleared the primary academic hurdle for the engineering department.
Engineering admissions officers look at the Math section first. For schools like MIT or Georgia Tech, the Math score is a filter. They need to know you can handle multivariable calculus and differential equations from day one. An 800 tells them that you have mastered the high school curriculum and are ready for university level rigor.
When you look at the 25th to 75th percentile ranges for the most competitive engineering schools, you will see that the Math scores are tightly packed. At many T20 schools, the 25th percentile for Math is often 780 or 790. By hitting 800, you are in the top tier of applicants. You have effectively "checked the box" for quantitative proficiency.
Many students panic when their English score is lower than their Math score, similar to the anxiety some feel when considering retaking the MCAT with high scores. However, admissions committees for engineering are realistic. They know that a student who is a genius at physics and calculus might not be a perfect poet. A 720 is still a very strong score (typically in the top 5 to 10 percent of all test takers). It proves you are literate, capable of reading complex texts, and can write clearly.
In the context of a T20 application, the difference between a 720 and a 760 in English is marginal for an engineering major. It is unlikely that an admissions officer will say, "This student has a perfect math score and a 4.0 GPA, but their 720 English score is too low for our Mechanical Engineering program." That simply does not happen. They are looking for a threshold of competence in English, and 720 is well above that threshold.
"I was stressed about my 1510 because my English was a 700, but I had a 790 in Math. I focused my energy on my robotics portfolio and my essays instead of retaking the SAT. I ended up getting into my top choice engineering school."
- Marcus, Mechanical Engineering Student
To understand if 1520 is enough, you have to look at how T20 schools actually make decisions. They use a holistic review process. This means they look at the whole person, not just a number, including their grasp of the foundations of software engineering and programming and whether studying computer science is risky if applying for CS. The SAT is used to ensure you can handle the work. Once you hit a certain number (usually around 1500 for T20s), the SAT stops being the deciding factor.
Think of the SAT as a threshold. If you score below 1450, you might be filtered out of the first round of reviews at an Ivy League school. If you score a 1520, you have passed the filter. Once you are past the filter, the admissions officer spends their time looking at other things. They look at your:
If you spend another 40 hours studying to move your English score from 720 to 760, you are spending 40 hours to gain a tiny advantage in one category. If you spend those same 40 hours polishing your common app essay or building a project for your portfolio, you are gaining a much larger advantage in a category that actually differentiates you from other high scorers.
The decision to retake depends on your specific goals and your current workload. For most students with a 1520 (800M), the answer is no. But there are a few exceptions.
You should stop testing if you are in the following situation:
A retake is only logical if:
Since your SAT is already in the competitive range, your focus should shift toward the parts of the application that you can still control. Engineering schools want to see "evidence of passion." They want to see that you don't just get good grades, but that you actually like building things.
For schools like CMU or MIT, a portfolio of your work is often more valuable than a 1600 SAT. This could include:
Avoid generic statements like "I have always loved math" or "I want to help the world." Instead, be specific. Talk about a specific problem you tried to solve. Describe the frustration of a circuit that wouldn't work and the satisfaction of finally finding the bug. This shows the admissions officer that you have the temperament of an engineer.
Once you move past the SAT, you will face a new challenge: the sheer volume of information in university engineering courses. The habits that got you a 1520 (like grinding practice tests) are not always the most efficient for long term retention in college. You need to move from "cramming" to "systems."
Active recall and spaced repetition are the most effective ways to learn complex material. Instead of reading a textbook three times, you should be testing yourself on the material. This is where automation becomes useful. Creating hundreds of flashcards by hand is a waste of time when you could be studying the actual content.
StudyCards AI solves this problem by allowing you to upload your PDFs and automatically generating AI flashcards that export directly to Anki. Whether you are preparing for the MCAT, the bar exam, or just your first semester of Organic Chemistry, this system removes the friction of card creation. You can focus on the actual learning process rather than the data entry of making cards.
For students aiming for T20s, time is your most valuable resource. Using StudyCards AI to handle the tedious parts of studying allows you to spend more time on your projects and essays, which we have already established are more important than a few extra points on the SAT.
Your 1520 is a fantastic score. You have the math skills required for the best engineering schools in the world. Now it is time to show them who you are outside of a standardized test.
No. While the average might be higher, a 720 is well within the competitive range. For engineering, the Math score is weighted much more heavily. As long as your English score shows you are proficient, it will not be the deciding factor in your admission.
Only if you have a very low GPA or weak extracurriculars and need a "perfect" score to compensate. If your other application components are strong, the difference between 1520 and 1550 is negligible. Your time is better spent on essays and portfolios.
They do not have a preference. They look at the percentiles. A 1520 SAT is roughly equivalent to a 34 or 35 on the ACT. Both are considered highly competitive for T20 schools.
No. An 800 Math score is common among MIT applicants. It is a requirement to be competitive, but it is not a guarantee of admission. MIT rejects many students with perfect math scores because they lack the creative projects or leadership experience the school seeks.
Use spaced repetition systems like Anki. By converting your textbooks and notes into flashcards using StudyCards AI, you can ensure you don't forget the core concepts before you start your university courses.
