ALEKS Initial Knowledge Check:
there is no answer key
ALEKS picks each question from how you answered the last one, so a list of answers from someone else cannot match yours. Here is how the check actually works, and what to do about the math it asks about.
- Why the questions differ from student to student
- The math it usually draws on
- How to practice — and get unstuck afterwards

The honest answer
Why there are no “answers” to find
The Initial Knowledge Check is the assessment ALEKS gives you when you start a course. It is not a fixed test. It is adaptive: ALEKS chooses each question based on how you answered the ones before it, so two students in the same class are unlikely to be asked the same things. An answer list from somebody else cannot line up with yours.
- 20–30questions in K-12 courses; 25 or fewer in higher ed
- No feedbackALEKS does not mark answers until the check ends
- Your paththe result decides which topics you start on
Here is the part most students miss: the check is not graded like an exam. Its only job is to find your starting point. When it finishes, ALEKS shows the result as a “pie” and builds the list of topics you are ready to learn.
Why copying backfires. A result that is better than your actual skills tells ALEKS you already know material you do not. It skips you past the topics you needed, drops you into harder ones that assume them, and you spend the semester stuck on problems built on something you never learned.
Not in a course yet? If you are about to sit the math placement test before college, that is a different assessment — see the ALEKS placement test guide.
So the real shortcut is not an answer key. It is walking in with the basics fresh, answering honestly, and then getting help quickly every time a learning topic stops you.
What it asks
The math the check draws on
The exact topics depend on the ALEKS course your instructor set up — prealgebra, college algebra, precalculus and so on. Most math courses draw on the foundations below. If one of them feels shaky, that is the one to practice before you start. Taking precalculus or trigonometry? The ALEKS trigonometry guide covers the trig topics, and geometry students can start with ALEKS proofs.

Try it on a typical problem
These are practice problems written in the style of the material the check draws on — not real ALEKS questions. Pick one and see how igni works: it checks each step you take and points at the line where something broke, and it never hands over the answer.

Upload your problem
Snap a photo, paste, or type any math problem you're stuck on.

2
Keep solving
Receive one hint at a time to help you keep solving — never the final answer.

Get it done
Complete the problem yourself and feel ready for the next one.
Work however you like. The check itself is one assessment; the learning topics after it take the whole semester. Solve them on paper or on your device — after each step, type your work or snap a photo and igni tells you whether that line holds up before you build on it.
Where it fits
When to use igni (and when not to)
igni never gives you the final answer — it checks your steps, the way a tutor looking over your shoulder does. Even so, a Knowledge Check is meant to measure what you know on your own, so keep igni either side of it.
-
Before the check
Warm up
Refresh fractions, equations and exponents so the check reflects what you actually know rather than what you have forgotten this week.
-
During a Knowledge Check
On your own
Answer honestly, and use ALEKS’s “I Don’t Know” when that is the true answer rather than guessing. An honest result is what puts you on the right topics — and many instructors require the check to be unaided.
-
After the check
Work your topics
Use igni whenever a learning topic or a homework problem stops you. That is the part of the semester where students actually get stuck.
Questions
Initial Knowledge Check FAQ
No. The check is adaptive: ALEKS picks each question based on how you answered the ones before it, so the set you get is built around your own answers. There is no fixed answer key, and a list from somebody else cannot be relied on to match your version.
It depends which ALEKS you are in. McGraw Hill describes a Knowledge Check in its K-12 courses as roughly 20 to 30 questions, and the Initial Knowledge Check in its higher-education math platform as 25 questions or fewer.
Either way the check adapts to you, so the exact number depends on how you answer.
Not during the check. ALEKS does not show whether an answer is correct or incorrect until the Knowledge Check is finished. You see the result afterwards, as your ALEKS pie.
Usually not. Most students take one when they enter a new ALEKS course.
It is a course setting rather than a fixed rule, though: an instructor can configure a course to carry existing progress over instead, in which case no new check is needed. Whether you get one depends on how your course was set up.
It is not a traditional pass-or-fail exam. Its job is to work out what you already know, what you still need, and which topics you are ready for — so a lower result mostly means you start further back, and your pie fills in from there.
Answering honestly usually gets you through the course faster, because you are not sent into topics that assume something you skipped. Your instructor may still set requirements of their own around it, so check what your course expects.
No. McGraw Hill says that if you log out part-way through a Knowledge Check, ALEKS saves your progress and you carry on from where you stopped when you sign back in.
Worth knowing if you are tired or short of time: stopping is better than guessing your way to the end, because the result decides which topics you are given.
Use the “I Don’t Know” option. It is there for exactly that, and it tells ALEKS something true about where you are.
Guessing — or getting help — does the opposite: it puts you into topics that assume something you have not learned yet.
It is how ALEKS shows your progress: each slice is a group of topics, and the filled part of a slice is what you have mastered. It updates as you learn topics and after each Knowledge Check.
We recommend you don’t. Knowledge Checks are meant to measure what you know on your own, and many instructors require them to be taken without outside help.
Use igni to prepare beforehand, and to work through your learning topics afterwards — that is where the semester is actually won.
