Unlike other languages, French used the English alphabet for most spellings, making reading and writing an easy task to learn. What French schools work on is the syntax of the language and the precise pronunciation of the words, which seem quite difficult. French courses come in varied difficulty levels. People with a good vocabulary in English, generally find it a tad easier to learn the French words. Like, appetite gets pronounced as appétit, cream gets pronounced as crème and so on.
It is important for a student to know the qualifications of a teacher and if the language being taught is the teacher’s native tongue. You also need to make sure that the course you do, is a recognised course and you can show it off on your resume. Also check the back ground of the French schools you choose since a lot of them take advantage of the popularity of the language and teach even though they themselves are not good enough to train others. Find out about part time courses, long term courses and courses for special requirements before you settle for the school of your choice.
