How to crack Contractor's license test?

I need help. I have taken the California Contractor's license test and have failed it. I have with me two 'Guaranteed' pass school books and they have been so useless for me. I am sole proprietor of a small construction company. My colleague advised me to join online program from Freedom Business School (http://ift.tt/28RngJw) to prepare for the License test. I need a second opinion. If anyone has any experience with the School, please share.

Thanks you very much.
