Need help with Syllogism

Have a test on Thursday. Need to master Syllogism by then.
A lot of problems can be solved very easily by using Venn Diagram. But not all.

So can anyone point me to some website(free) or ebook or video where the Syllogism rules are explained in an easy manner?

Note: I have R.S.Agarwal. But cannot decipher the meaning of the rules given there.

Kenneth H Rosen ?

And I find converting them to logical statements & solving is less time consuming

Which book written by Kenneth H Rosen should I follow?

And can you give some examples of converting given statements into logical statements?
