I don't know where to start but in one sentence this a site which gives us quality education for free by experts from well known universities. I am also doing those programmes and I can assume you its worth it and you can learn all the things for free, just to validate certificate you have pay a amount. There are so many categories which you can't learn from elsewhere for free. So I am telling you if you wants to learn anything just go for this site.
