I found this course informative as far as grammar, or technical English goes. The videos were also informative. You also receive ready made material to use in classes and these are given as part of the course. In general, I had the feeling that a lot of corners were cut to produce the course. It's very basic, bordering on primitive in terms of presentation. It's a no-frills course for sure, and if you know next to nothing about the English language, then this is a place to get you started. The value of the certificate depends on which country you present it in. In Europe, it's not really known and it has a lot to do with who you know if you decide to use it to get into language schools. My recommendation is to do it, get the certificates but then go on to a CELTA course which is internationally recognized and what you will need to not just know your nouns from your verbs, but will also ready you for an actual class. Good luck!
