I asked the tutor several college level electronics questions. Not only were they unable to answer them, the tutor could not even start them. I requested a refund of the initial trial fee and they never replied to my e-mail. I received my credit card statement this week and not only did they charge me for the one week trial they charged me for a whole year in addition. This is a scam and they just take your money without providing any reasonable services.
