Linear Algebra True/False Practice

How this works

You'll see a statement about linear algebra and decide whether it's true or false. Some questions then ask which reason is the right one. Either way you'll get an explanation — worth reading even when you answered correctly.

This is meant to be low-stakes practice. There is no grade attached.

This opens a Google form with the question and your answer already filled in. Describe the problem there, then press Submit to send it. That one Submit is all it takes.

The form asks you to sign in, and a Wake Forest account works, so your report will be identified. Nothing else about your practice is sent — your history stays in this browser.

Does this count for a grade?

No. Your practice answers and history are recorded only in your own browser unless you choose to report a question.

What am I supposed to do?

Read each statement and decide whether it is true or false. Sometimes you'll then be asked which reason is the right one. Either way, read the explanation afterwards — including when you answered correctly, since that's where most of the point is.

Why are some questions so picky?

Because the picky part is usually the point. A theorem can stop being true when one hypothesis is dropped, and two statements that look nearly identical can differ in the single word that decides them.

I think a question is wrong.

Please say so. Underneath any explanation there's a Report a problem link. Reports get read, and questions do get corrected.

Will this get me ready for the exam?

It helps with definitions, theorems, and telling apart statements that look alike. It won't replace working problems by hand.
