Choose carefully..
Be very careful before putting your hard earned cash into any of these courses you find online. Many of these so-called universities and schools are not accredited, they also come with dubious titles that don't correspond to the subject matter being taught. Take this 'flying birds' place mentioned above. A quick look at their website shows that they are located in India; not very practical for those outside of India and the courses offered appear to lack any real subject matter. They also have their company email addresses with Gmail; how professional is that!
Check to see who the lecturers and tutors are. Are they known in the industry? Are they qualified to be teaching you? some of them aren't qualified to teach a dog to sit!
You should also bear in mind that properly accredited schools are the only ones who tie in with the government's education schemes that can benefit those out of work, mature students or those on low incomes so alot of foreign schools, whether they are accredited in their home countries or not, will be unlikely to qualify for this.
Do your research and when it comes to the school you choose; there are lots of unqualified people out there posing as educators, operating out of their living rooms and only too happy to swap your cash for an unrecognised qualification.
Finally, ignore some of these shameless plugs for useless schools (the word 'school' used very loosely) selling useless pieces of paper and go do your own digging.
