Try to check the school out carefully first. Try searching for the name of the school + blacklist, which might bring up any complaints about it. If there are a number of complaints, especially with repeats of the same problems, it might be a place to avoid. If you want to do the job for any period of time, then get qualified- without qualifications, your choices are restricted and you are more likely to find yourself working for one of the sharks.
