Kenny, you are in the right place for supplementing your training, but you should show your answers and why you think they are correct instead of just asking the members to give you the answers.

Keny;

Please do as Roger has mentioned, and post your results + what led you to the answers.
Otherwise we cannot assist you!

We need to know where you're having conflicts first, so post what you think are the answers and we will expand on those items.

We WILL NOT answer exam questions! Instead, we will make the answer "Apparent" to you.

p.s.: did you draw the images shown in your post?
