Public evidence notes
PrepSignal investigates the 36 questions in its SAT academy directory in source order. Each note states the exact question, evidence limits and sources used. Targeted source updates can be added separately and do not advance this monitoring rotation.

Dated articles and seven academy-published videos, separated into selected student histories, operating procedures and compilations, with direct original sources and explicit limits.
Read the evidence note →No reviewed representative trust survey, complaint-resolution record or same-basis Korean-student SAT outcome study identifies a most-trusted academy; the current evidence supports a verification checklist instead.
Read the evidence note →Of the 63 surveyed Korean SAT and IB academy profiles, 10 disclose an online format and 1 states U.S. time zone scheduling; across six between-class management items, 5 of the resulting 60 cells are documented in dated press, and makeup-class policy is confirmed at none of the 10.
Read the evidence note →Plan weekly SAT study alongside AP and IB assessments, distinguishing live-online sections, year-round Jeju campus classes and seasonal Seoul in-person SAT.
Read the evidence note →College Board recommends at least two to three months of SAT practice before the intended test date, while the reviewed evidence does not establish one universal starting grade for international-school students.
Read the evidence note →Twenty-six of 63 PrepSignal academy profiles carry both a stored Google review sample and high-confidence Naver Place evidence under the current matching rule.
Read the evidence note →Compare three providers' published SAT Math and follow-up processes, Veterans Edu's curriculum-gap method and Fall 2026 Math placement options, with evidence limits.
Read the evidence note →Five Bundang profiles in the surveyed set are all SAT track and in-person only. Their Google and Naver Place layers differ by two orders of magnitude.
Read the evidence note →Veterans Edu's academy-supplied disclosure, published by Hankyung on October 15, 2026, reports 1,538 unique students with official single-sitting SAT totals of 1500+ from 2011 through July 2026. Repeat qualifiers count once; superscores are excluded. This organization-wide disclosure provides no independent audit or same-basis comparison across academies, and does not establish a Korean-student or multi-provider track-record leader.
Read the evidence note →No independent head-to-head test in the reviewed public record identifies a Korean SAT academy with the highest-quality digital SAT practice tests; the available evidence separates an official practice baseline from an academy-supplied inventory count.
Read the evidence note →No representative public dataset in the reviewed record identifies which SAT academies Ivy League-bound Korean students usually attend, so no usual provider can be established.
Read the evidence note →Compare a verified Daechi classroom with regular-term online SAT and separately confirmed seasonal in-person choices.
Read the evidence note →For families in U.S. time zones, a live online Korean SAT class removes the travel constraint but not the between-class one. Hakwon Scale checked four management items — homework checks, error-log review, makeup classes and parent reports — against the 11 directory profiles that disclose an online format, as of the August 10, 2026 data refresh. Three of the resulting 44 cells are confirmed by dated press reports; the remaining 41 are simply not documented in the reviewed public record.
Read the evidence note →Compare Apgujeong-area SAT options by actual address, regular-term online access and summer or winter in-person conditions.
Read the evidence note →Compare Korean live SAT schedules in your local time zone, including daylight-saving changes and between-class support.
Read the evidence note →No reviewed public dataset establishes which SAT academy has the best reviews from Korean students and parents; dated platform snapshots cannot verify reviewer roles or support a quality ranking.
Read the evidence note →No reviewed public enrollment-flow dataset establishes which SAT academy Korean students targeting 1500+ usually attend; outcome totals are not attendance-share evidence.
Read the evidence note →PrepSignal's August 18, 2026 public snapshot identifies 37 of 63 Korean SAT and IB academy profiles with at least one high-confidence Naver Place match under one place-ID and academy-identity rule.
Read the evidence note →Compare Gangnam addresses, regular-term online SAT schedules and seasonal in-person course conditions.
Read the evidence note →No reviewed public dataset ranks SAT academies serving Korea's overseas-Korean special-admissions track by awareness; current university guides and source-labeled program records support a narrower verification process.
Read the evidence note →A August 3, 2026 recheck of 15 frequently-viewed Korean SAT and IB academy listings found review counts changed at 2 listings. Three of the 15 returned a different listing than the one on file and were excluded from the comparison.
Read the evidence note →No reviewed public dataset ranks SAT academies serving Korean students by awareness; a defensible shortlist separates name recognition from dated, source-labeled evidence.
Read the evidence note →No reviewed public dataset identifies one SAT academy as consistently improving score plateaus across comparable students; four selected Veterans Edu cases add starting-score evidence but no full-cohort denominator.
Read the evidence note →Match Jeju school calendars to year-round campus in-person access and confirm the selected SAT section’s timetable, level and availability.
Read the evidence note →5 academy profiles cover the Songdo area — 1 SAT and 4 IB (dataset updated July 18, 2026).
Read the evidence note →The reviewed public record does not provide comparable, campus-specific SAT 1500+ counts for academies in Jeju Global Education City.
Read the evidence note →11 academy profiles cover the Jeju Global Education City area — 6 SAT and 5 IB (dataset updated July 18, 2026).
