how to see a friend's post on facebook timeline?

[M]

because of less time of studying for our test, my teacher made a powerpoint presentation about the lesson but the bell already rang so he wasn't able to finish. He told us that he would be posting the powerpoint presentation on facebook. i tried looking for the link and couldn't find it T_T

how could i find it?

You only have to ask your teacher where did he post it. It might be on a page, on his account or somewhere else.
