Do one-step equations, percents, equivalent expressions and exact answers with roots or pi by hand. The full table, with the move, the time it saves, and the trap on each side. sat-tips https://sightlineprep.com/blog/digital-sat-vs-paper-sat/ https://sightlineprep.com/blog/digital-sat-vs-paper-sat/ Fri, 16 Oct 2026 00:00:00 GMT The SAT went fully digital in the US in March 2024. It is an hour shorter, adaptive, has a calculator on every math question, one short passage per reading question, and scores in days. The same 400 to 1600 scale. A side-by-side table and what each change means for a student preparing now. sat-tips https://sightlineprep.com/blog/question-review-circle-three-points/ https://sightlineprep.com/blog/question-review-circle-three-points/ Mon, 12 Oct 2026 00:00:00 GMT A circle passes through (0, 0), (6, 0) and (0, 8). Find its radius. Desmos fits it in a table in twenty seconds. By hand it is perpendicular bisectors and a minute of algebra, unless you notice the triangle, in which case it is ten seconds. Both ways, timed, and what that says about when to graph. question-review https://sightlineprep.com/blog/command-of-evidence/ https://sightlineprep.com/blog/command-of-evidence/ Fri, 09 Oct 2026 00:00:00 GMT 'Which finding, if true, would most directly support the hypothesis?' and 'Which choice most effectively uses data from the table?' are the longest questions in the Reading and Writing module and the ones students run out of time on. The two tests every choice has to pass, and the trap built into each version. sat-tips https://sightlineprep.com/blog/bluebook-tools-worth-practicing/ https://sightlineprep.com/blog/bluebook-tools-worth-practicing/ Mon, 05 Oct 2026 00:00:00 GMT The digital SAT's testing app has nine tools. Three of them change how you take the test, two are worth a few minutes each, and the rest you can leave alone. Which is which, what the reference sheet does and does not contain, and the two-pass method the question menu makes possible. sat-tips https://sightlineprep.com/blog/what-is-a-good-sat-score/ https://sightlineprep.com/blog/what-is-a-good-sat-score/ Fri, 02 Oct 2026 00:00:00 GMT The national average for the class of 2026 was 1045. A 1200 is the 75th percentile among test takers, a 1400 the 93rd, a 1500 the 97th. None of those is the answer, because the only score that is good or bad is one measured against a particular college's admitted range. college https://sightlineprep.com/blog/student-produced-responses/ https://sightlineprep.com/blog/student-produced-responses/ Mon, 28 Sep 2026 00:00:00 GMT Several questions per math module have no choices, just a box. Negatives are allowed now, mixed numbers are not, and 0.67 is wrong when .667 is right. The official rules, the examples College Board publishes, and the two Desmos habits that make the box safe. sat-tips https://sightlineprep.com/blog/words-in-context/ https://sightlineprep.com/blog/words-in-context/ Fri, 25 Sep 2026 00:00:00 GMT The vocabulary questions on the digital SAT are the first few in every Reading and Writing module. They are not testing whether you know big words. They are testing whether you can tell which ordinary word the sentence needs, and there is a way to do that before you look at the choices. sat-tips https://sightlineprep.com/blog/question-review-constant-as-y/ https://sightlineprep.com/blog/question-review-constant-as-y/ Mon, 21 Sep 2026 00:00:00 GMT 3x² − 36x + k = 0 has exactly two real solutions. For what values of k? By hand it is the discriminant and some arithmetic that is easy to get wrong. In Desmos it is one line, if you know not to type the k. Both ways, timed. question-review https://sightlineprep.com/blog/sat-vs-act-2026/ https://sightlineprep.com/blog/sat-vs-act-2026/ Fri, 18 Sep 2026 00:00:00 GMT The ACT got shorter and made science optional, the SAT went digital and adaptive, and every Ohio junior gets one of them for free at school. What each test looks like in fall 2026, how to compare a student on both, and the one decision that actually matters. college https://sightlineprep.com/blog/practice-test-at-home/ https://sightlineprep.com/blog/practice-test-at-home/ Sat, 12 Sep 2026 00:00:00 GMT A full-length Bluebook practice test is the best free thing College Board gives you, and most students waste it by taking it in pieces. The conditions that matter, the ones that do not, and the one number the report will not give you. sat-tips https://sightlineprep.com/blog/rhetorical-synthesis-questions/ https://sightlineprep.com/blog/rhetorical-synthesis-questions/ Sat, 12 Sep 2026 00:00:00 GMT Rhetorical synthesis questions hand you a list of notes and ask which sentence uses them to meet a goal. Most students read the notes first. That is backward, and it is why these take ninety seconds instead of thirty. sat-tips https://sightlineprep.com/blog/psat-to-sat/ https://sightlineprep.com/blog/psat-to-sat/ Fri, 11 Sep 2026 00:00:00 GMT The PSAT is scored on the SAT's scale and tests the same skills, so a score is a fair estimate of an SAT taken the same month. It is a poor estimate of the SAT you will take in March, and it cannot see the top of the range at all. What to take from the report. college https://sightlineprep.com/blog/question-review-extraneous-root/ https://sightlineprep.com/blog/question-review-extraneous-root/ Mon, 07 Sep 2026 00:00:00 GMT Solve √(2x + 3) = x by hand and you get two answers, one of which is wrong. Graph it and you get one. The same question worked both ways, with the clock running, and what it is actually testing. question-review https://sightlineprep.com/blog/test-optional-2026/ https://sightlineprep.com/blog/test-optional-2026/ Fri, 04 Sep 2026 00:00:00 GMT As of September 2026 the Ivy League is back to requiring scores, the Florida and Georgia public systems are phasing them in, and most of the rest of the top 100 are still optional. What each policy word actually means, and how to decide school by school. college https://sightlineprep.com/blog/desmos-when-to-put-it-down/ https://sightlineprep.com/blog/desmos-when-to-put-it-down/ Mon, 31 Aug 2026 00:00:00 GMT The first thing I teach about the built-in calculator is when not to reach for it. A rule for deciding in five seconds, the eight situations where graphing costs time, and the six traps that turn a right method into a wrong answer. sat-tips https://sightlineprep.com/blog/transitions-questions/ https://sightlineprep.com/blog/transitions-questions/ Fri, 28 Aug 2026 00:00:00 GMT 'Which choice completes the text with the most logical transition?' appears several times per module. The five relationships it tests, the words that belong to each, and why reading the choices first is how students get these wrong. sat-tips https://sightlineprep.com/blog/punctuation-the-sat-actually-tests/ https://sightlineprep.com/blog/punctuation-the-sat-actually-tests/ Fri, 21 Aug 2026 00:00:00 GMT Boundaries questions look like grammar and are really about one thing: where a complete sentence ends. Semicolons, colons, dashes and commas, with the single check that settles nearly all of them. sat-tips https://sightlineprep.com/blog/desmos-on-the-digital-sat/ https://sightlineprep.com/blog/desmos-on-the-digital-sat/ Fri, 31 Jul 2026 00:00:00 GMT The graphing calculator sits in the test app on every math question. Here are the six situations where it turns a two-minute algebra problem into a ten-second one, and the two where reaching for it costs you time. sat-tips https://sightlineprep.com/blog/when-to-start-sat-prep/ https://sightlineprep.com/blog/when-to-start-sat-prep/ Thu, 30 Jul 2026 00:00:00 GMT Work backward from the test date rather than forward from today. A guide to picking a first test date, how long each stage actually takes, and why starting too early usually backfires. college https://sightlineprep.com/blog/how-to-review-a-practice-test/ https://sightlineprep.com/blog/how-to-review-a-practice-test/ Wed, 29 Jul 2026 00:00:00 GMT Going through the questions you missed is the least useful review you can do. Here is the order that finds the points, and the four categories every question should be sorted into. sat-tips https://sightlineprep.com/blog/why-official-practice-tests-only/ https://sightlineprep.com/blog/why-official-practice-tests-only/ Tue, 28 Jul 2026 00:00:00 GMT Unofficial SAT practice tests are scored on curves nobody has validated, which is why a student's score can swing 150 points between two companies in the same week. What they are good for, and what they are not. sat-tips https://sightlineprep.com/blog/how-many-hours-of-sat-tutoring/ https://sightlineprep.com/blog/how-many-hours-of-sat-tutoring/ Mon, 27 Jul 2026 00:00:00 GMT A straight answer from the tutor you would be paying: what the number depends on, when more hours stop helping, and the three situations where tutoring is the wrong purchase entirely. college https://sightlineprep.com/blog/how-the-adaptive-digital-sat-works/ https://sightlineprep.com/blog/how-the-adaptive-digital-sat-works/ Sun, 26 Jul 2026 00:00:00 GMT The digital SAT gives every student a second module chosen by how they did on the first. Here is what that routing does to your score ceiling, and the three study habits it makes obsolete. sat-tips https://sightlineprep.com/blog/pacing-on-the-digital-sat/ https://sightlineprep.com/blog/pacing-on-the-digital-sat/ Fri, 24 Jul 2026 00:00:00 GMT Why per-question timing catches the plateau that practice-test scores hide, and how to tell a pacing problem from a content problem on the digital SAT. sat-tips
