Can I understand correctly?

For example, just for example,
Did I create exam and prepare exam and test myself? Let me said it correctly. I create the exam and prepare the exam and make a exam and test myself.

Can Have I understand understood correctly?

For example: just for example,

Did I create the exam and prepare the exam and test myself?
Let me said say it correctly.
I create the exam and prepare the exam and make an exam and test myself. This entire sentence makes no sense.

I'm really not sure if you've understood or not.

If you created the questions that form the exam, you could say "I prepared the exam".
If you answered the questions in an exam, you could say "I prepared for the exam" (by studying and revising).

It's quite difficulties to understand @Lycidas statements. I can't catch the point.

 

[emsr2d2]

It's quite difficulties difficult to understand @Lycidas statements. I can't catch don't understand their point.

Put more simply, "prepare an exam" means "make/write an exam" (creating the questions ready for someone else to actually take/sit the exam). The "you" in your question must be the person who did that, not a student who answered the questions on the exam.

If you created the exam, wouldn't you test it (the exam) to check that you hadn't made any mistakes? If you created it, it wouldn't be a way of testing yourself.
