So I had to study in the way of tries and mistakes. However I got enough knowledge to create and to run my own site. In general, there's nothing to be scared of. You must have a motivation, and the necessary result can be achieved - naturally if the result is extremely necessary. All began from E-Mail.
Mail is mail, but the bothering idea of megabytes laying without use periodically appeared.
However, this statement should not be so categorical any more. As far as I know, results of testing by Tekmetrics are quoted highly enough and are seriously considered by potential employers. It is the first attribute of real examination - to pass is not easy. It was politely recommended to me to read reference books and try again. Probably, that one point is equal to 8 right answers as the greatest possible score is 5.0.
