For each theorem, make sure you understand the general idea of how the proof works, rather than trying to learn it by heart.

Then practice getting it down on paper.

You don't have to have it off by heart or have it exactly as per the book. It's best if you have the notation correct, but the main thing is to get the bare bones of it down. You can tidy up the notation once you have it down on paper.

Try this out with one or two theorems, and then build up to mastering the rest.

Here's the list of the ones you need:

JCO - no theorem proofs required

JCH - 4, 6, 9, 14, 19

LCO - no theorem proofs required

LCH - 4, 6, 9, 11, 12, 13, 14, 19 (which is really the 5 JCH ones plus 11, 12, 13)

Hope it helps!

thanks everyone! :)

Correction: for LCH, you don't need to know the proofs of the JCH theorems. So it should be:

Here's the list of the ones you need:

JCO - no theorem proofs required

JCH - 4, 6, 9, 14, 19

LCO - no theorem proofs required

LCH - 11, 12, 13

the best thing how to learn them is to understand them. If u dont understand them u will not learn them
