Test & EducationAugust & September SAT® Results Report
We compiled the August and September SAT results for 17 of the 18 students in our Summer 2026 SAT program. Rather than hand-picking the best outcomes, we laid out all 17 students' data as averages and distributions, including the students whose scores went down.
How we measured
- First test
- The in-house diagnostic test each student took on joining the program
- Last 3 mocks
- The average of the final three practice tests before the official SAT
- Best score
- The higher of the Saturday, August 22 and Saturday, September 12 SAT scores
- Sample
- 17 of 18 participating students (one was excluded because we could not obtain their official score)
Results
The average first-test score was 1199; the average best official score was 1351. Of the 17 students, 13 improved, 1 stayed the same, and 3 dropped. All 13 who improved gained at least 100 points, and the largest gain was 320 points.
On the first test, 2 students scored 1400 or higher. On the official SAT, 5 students scored 1400+, and 3 of them scored 1500+.
The median (+180) is higher than the average (+152) because the three students whose scores dropped pulled the average down.
Comparing start dates
| Started early summer | Started late summer | |
|---|---|---|
| Students · length | 10 · 10 weeks | 7 · 5 weeks |
| Avg. first test | 1203 | 1194 |
| Avg. gain | +174 | +120 |
| Median gain | +215 | +110 |
The two groups' first-test averages were only 9 points apart. Starting from the same level, the group that used all 10 summer weeks gained 54 more points on average, and 105 more at the median. Looking only at the 8 early-summer students who joined in week one, the average gain was +241. Even so, the late-summer group, with just 5 weeks, still gained 120 points on average. The size of the gain tracks the time available.
Math vs. Reading and Writing
By section, the difference is clear. 16 of 17 students improved in Math. Drilling concepts and solving tools (by hand, calculator, Desmos) pays off well for the time invested.
In RW, 4 of 17 students actually went down. Reading comprehension moves only as fast as a foundation in vocabulary and sentence structure builds up, so it is hard to shift much in a short time.
💡 YEON Insight
The fastest way to raise an RW score is to practice grammar (Standard English Conventions) and Transition questions until you get nearly all of them right, then spend the time you save on the harder reading questions. With 100% accuracy on the Writing questions, a student can secure a 650 even while getting only half of the Reading questions right.
Practice test average vs. official score
14 of 17 students scored higher on the official SAT than their mock average.
Broken down by start date
| Start | Official > mock | Official < mock |
|---|---|---|
| Early summer (10) | 8 | 2 |
| Late summer (7) | 6 | 1 |
Why did three students score lower on test day?
For all three, most of the gap came from RW: they averaged 154 points below their mocks in RW, but only 9 points below in Math. These are the likely causes as we see them.
- Easy Module 2. The digital SAT is adaptive: how a student does on Module 1 sets the difficulty of Module 2. Miss a few questions in the first module and get routed to the easier Module 2, and the ceiling on the score drops no matter how well the student does afterward.
- First-test nerves. For all three, this was their first official SAT, and two of them had their August test canceled by their test center, making September their first real sitting. The test center, proctors, and devices can't be fully recreated in a practice test. Students who practice online should rotate their practice to places where they can focus completely, like a library.
💡 YEON Insight
Don't judge a student's ability by a single practice test score. What matters is the average of at least three, the trend in each section, and which direction the gap between practice and official scores runs. Students whose mocks run higher than their official scores need RW Module 1 accuracy and test-day execution training; students whose mock scores swing need consistency.
August vs. September
13 of the 17 students took both the August and September tests. The tests were three weeks apart, and the average score rose from 1312 to 1353. Both sections rose evenly, RW by 18 points and Math by 23, and the largest gain was 100 points.
Two students dropped. One of them had already scored 1500 in August; their September score was 30 points lower, but the August score stands as their best.
Of the 4 students who took their first official SAT in September, 2 scored more than 170 points below their mock average in RW. Both had their August test canceled because of issues at the test center. That is a clear contrast with the students who already had one official sitting behind them from August.
What test-takers said
Students who sat the test saw it a little differently. Right after the September 12 test, the most common reaction in Reddit's SAT community was that Math Module 2 was harder than August's. Opinions on RW were split: many found the passages easier to follow than August's but the vocabulary questions tougher, and some said they ran short on time in Module 2.
Even on a test that felt harder, our students' September Math scores rose 23 points on average from August. For reference, the College Board corrects for differences in difficulty between test dates through score equating, so a test that feels harder does not put students at a scoring disadvantage.
💡 YEON Insight
A student's first official SAT is both a scored test and a first taste of real test conditions. When 11 of 13 students improved on their second attempt, it was less because their skills surged in three weeks than because they had adjusted once to test-center nerves and the module structure. That is why we plan every schedule around two sittings from the start.
What 17 students' data tells us
- Time is the biggest variable. From the same starting line, the 10-week group gained 54 more points on average than the 5-week group. When you start is your strategy.
- Plan Math by the semester and RW by the school year. The two sections improve at different speeds.
- Plan for at least two official sittings. 11 of the 13 students who tested twice improved on their second try, adding 41 points on average.
