Hey,

You need to get a Tourist Visa. Depending on the country you are coming from these can last different lengths. Most at least three months. 42 is not an accredited school so you can not get a student visa. People who stay longer than six months, usually go to a college for learning English that is accredited and get two stay for two years. They all speak english already, just do this to stay in country.

The first two days are Linux, the rest are coding in C. It is designed to make you fail... a lot! No one knows how they decide who gets in, but three things seem to be important. Do all the exams, spend at least 10-15 hours in lab every day, try to improve.
