Online Life & Health Courses - Which One has high pass %

I have spent a day just looking into what online life and health courses are available for NC. I am familiar with the insurance industry but have never taken the exam yet. I need an online course with the Pre-Test that will help me pass the first time. I have 30 days to get this done. Needs to be online because I have regular business during the day so I can't take a classroom course. I have seen more bad then any real good comments about different companies. Need feedback from experienced professionals about 360training.com (same as learninsurance.com) also Kaplan. or any others for NC that you may have input on that are good.

Thanks in advance for your advice!
