How to take an SAT practice test at home so the score means something

Every student I work with starts with a full official practice test at home, before we have spent an hour together. Most families have already done one by the time they reach me, and most of those scores are not worth much. The test was fine. The way it was taken was not.

The difference between a practice test that tells you something and one that does not is almost entirely about conditions. Here is what actually matters.

Use the real thing

The test is in Bluebook, the same app used on test day, and it is free. The full-length practice tests inside it are written by College Board, scored on College Board’s scale, and adaptive in the same way the real test is: the second module you get depends on how you did on the first.

Nothing else is a substitute. A third-party practice test is scored on a curve nobody has validated, and a student’s score can move a hundred points between two companies in the same week. I have written about that separately; the short version is that if the score is going to drive any decision, it has to come from Bluebook.

One sitting, with the break

The real test is two Reading and Writing modules, a ten-minute break, then two math modules, about two and a quarter hours in all. Take the practice test the same way: all four modules in one sitting, the break where it falls, and nothing else.

This is the rule students break most, and it is the one that matters most. Reading and Writing on Tuesday and math on Thursday is two tests, not one, and the math score in particular comes out higher than it would after an hour and a half of reading. A practice test exists to find out what happens to your accuracy in the third hour. You cannot find that out by not having a third hour.

Do not pause. Bluebook will let you; the real test will not.

Morning, phone in another room

The SAT starts around eight in the morning. A practice test at nine at night after school and practice measures something, but not what the real thing will measure. A weekend morning is ideal.

Phone out of the room, not face down on the desk. Notifications are not the problem; the habit of checking is, and the one time you look is the one time your timing on a question becomes meaningless.

What to have

• A laptop or tablet with Bluebook installed and the test downloaded. Do this the night before, not at 8:55.
• Scratch paper and a pen or pencil. You get these on test day, and students who work everything on screen because they did not think to grab paper lose time on the math.
• Nothing else. No outside calculator. The graphing calculator built into the app is what you will have on test day, and learning it is part of the point. No notes. No looking anything up.

What does not matter

The room. A kitchen table is fine. Whether it is exactly the same time as the real test to the minute. Whether you feel ready. You are not supposed to feel ready for the first one; it is a measurement, not a performance.

Do not retake a test you have seen

A student who takes Practice Test 1 in September and again in November is measuring memory. Bluebook has several full-length tests; use a new one each time, and do not burn through them. One every three to four weeks is plenty. The work happens between tests, and a student taking one every weekend is practicing taking tests rather than getting better at the material.

What the report gives you, and what it does not

When you finish, the score appears in Bluebook and the full breakdown lands in My Practice on College Board’s site: every question, your answer, the right answer, and which skill it tested. That is useful, and it is free.

What it will not tell you is how long each question took. That is the number I care about most, because a question you got right in ninety seconds is not a strength. It is a wrong answer you have not gotten yet, and it is the reason practice-test scores plateau while a student keeps working. The only way to have that number is to log it, which is what every student here does on their first test and every test after.

What the score means

Take a real practice test under these conditions and the score is a fair estimate of what you would get on test day that week, within about thirty points either way. That is the number to plan from, not the one from the test you took in two halves with your phone on the desk.

If the first one is lower than expected, that is the test doing its job. It is much better news in September than in the score report in March.
