    Dear Sir,
    Oh my god, your website really helps me a lot of preparing myself for the final exam on 20/03/2012. I found that your material becomes great assets to help me to make better grades which I am concerning all about the exam paper what are gonna be.

    Personally, I really love your website and materials available are so meaningful. From now to March 20, I would sleep well as my hope since I have sleeping less and be patient with talkative professor.. I’ll kick him ass if I get better grade. I strongly believe that your website is very interesting and feel fun while studying on your material. It is good words for example, like kick the professor ass and let him speakless!

    Thank you very much,
    Best Regards,

    Hi David,

    I was just wondering about all the premium videos. So if I pay one amount I can access all of them? or do i have to pay for each and everyone of them.

    How much would it cost to access all the premium videos? And how do i do it?

    I saw your free videos and i love them!

      Hi Val, you just pay one amount to access all of them. There are many plans, from $97/month for unlimited access to $29.95 for 20 hours within 3 months (can watch 10 hours this month, another 7 hours next month, another 13 hours for the 3rd month; divide it up the way you want), as well as lower plans. The $29.95 or 19.95 plans are good enough for most people and most people with the 20-hour plan still end up with leftover hours in the end. Cheers
