Look for a good instructor rating school,
How can you be certain it is a good school? That is the problem for anyone looking to find "good" schools.
And even if you judge the school on how many gold stripes the instructors wear on their shoulders, the size of their mobile phone (used to be the size of their wings and watch)and only go for the most expensive (or the least expensive), you are still totally reliant on the personality and skill of the instructor who is allotted to you; or who answers the telephone first and grabs you as his student. Best of luck on that one
