Select ALL That Apply Means Check EVERY Choice

Say you're twelve minutes into a Quant section. The question ends with Indicate all such values. You test choice B, it works, you click the box, and you're gone. Next question. You feel fast. You feel sharp.

You just threw that question away.

I'll bet you've done this at least once in your practice, and I'll bet you didn't notice until you checked the answer and saw that C and F were also right. It's one of the most common ways I see people leak points on the GRE, and it's one of the easiest leaks to fix. You don't need to know more math. You need to stop quitting halfway.

Why one right answer is worth nothing

Most GRE questions give you round ovals and one right answer. A select-all question is different. It shows square boxes instead of ovals, and more than one box can be right. In Quant, ETS calls these multiple-answer questions. In Verbal, they show up in Reading Comprehension (the questions about a passage), usually with three choices where one, two or all three can be correct.

Here's the rule that matters. You get credit ONLY if you pick every right choice and no wrong ones. There is no partial credit. ETS says so plainly on its Quant section page. Two right boxes out of three earns the same as zero right boxes. Nothing.

Stop reading for a second and think about what that means. On a normal question, finding the right answer is the finish line. On a select-all question, finding ONE right answer is just the first checkpoint. If you stop there, you did most of the work and got none of the reward. That's like running 20 miles of a marathon and then sitting down on the curb.

And it costs you twice. The GRE is adaptive section by section, which means how you do on your first Quant section decides how hard your second Quant section will be. Points you leak early don't just vanish. They shape what comes next. (More on that in Your First Section Sets Up Your Second. Act Like It.)

Checking every choice does NOT have to be slow

The usual excuse is time. "If I check all eight choices, I'll run out of time." Look at the example again. The hard part was Step 1, finding the rule. That took maybe 30 seconds. After that, each choice took about three seconds. Checking all eight cost you well under half a minute. Skipping them cost you the whole question.

So here's the method:

• Solve the rule once. Don't re-solve the problem from scratch for each choice. Figure out what a right answer has to look like, write it down, and then compare.
• Write the letters on paper. A, B, C, D and so on, down the side. Every letter gets a mark: Y, N or ?. No letter leaves the page blank.
• Use estimation where you can. Many choices die in a second because they're way too big or way too small. You don't need the calculator to kill those. (See Estimate FIRST, Calculate Second (If At All).)
• Come back to the ? marks. You can mark a question and return to it later in the same section, so a ? is fine. A blank is not.

Verbal does the same thing to you

In Reading Comprehension, the select-all questions feel easier because there are only three choices. That's exactly why people get lazy on them. Try this one.

The mistakes I see every week

1. Stopping at the first right answer. You find one that works and your brain says "done." It isn't done. INSTEAD: make it a hard rule that you never click Next on a square box question until every letter on your paper has a Y or an N.
2. Guessing how many are right. "It's usually two." "It can't be all of them." Says who? Unless the question tells you how many to pick, it could be one, it could be every choice. INSTEAD: judge each choice on its own, as if the others didn't exist. That's literally what the Verbal directions tell you to do: consider each choice separately.
3. Doing it in your head. Holding eight verdicts in your memory while you work is how you lose track of whether you already checked F. INSTEAD: write the letters down. Every time. Refusing to take notes isn't speed, it's pride, and pride is expensive here.
4. Re-solving the whole problem for each choice. This is what makes select-all feel slow. INSTEAD: find the rule once (like |x| is 2, 3, 4 or 5), write it down, and then each choice becomes a quick yes or no.
5. Reading "could" as "must" (or the other way around). "Which could be the value" and "which must be true" are totally different questions. Mix them up and you'll pick the wrong set even if your math is perfect. INSTEAD: write the key word, COULD or MUST, at the top of your notes before you look at a single choice.

Notice that none of these mistakes are about being bad at math or bad at reading. They're about process. That's good news, because process is the part you can train.

Your move today

Go back through the practice questions you've already done and pull every one with square boxes. Redo them. Not for the answer, for the process: letters on paper, a rule found once, a verdict on every choice. Then count how many you originally got wrong because you stopped early or skipped a choice you never really checked.

I'll bet that number is LARGER than you think. And every one of those is a point you already had the skill to earn. Go get them back.
