Don't be surprised that the tests have been re-numbered again. 220-221 & 220-222. They are the same tests/requirements as the numbers you posted.
If you are short on time, then go to the questions at the end of each chapter. Answer the questions. If you miss any one question, then go back and read the chapter. If you answer all the questions, go to the next chapters questions and see if you can do the same.
Otherwise, go through the practice tests and practice.
If you have experience in the field, you should not have any problems with the tests. If this is all new to you, then go through everything.
If you can learn by going through study guides, then go ahead and do what the previous answer posted. But, I tend to understand the material when reading through the stuff... if you have time, that is the best route to take.
