Some people here might say that these schools will let anyone in just to take their money - but I am pretty sure that all these schools offer money back guarantee if you fail the course. So it is actually in their best interest to only let people join the school if they think they are capable of completing the training.
Nevertheless, it’s probably a good place to start, because they will assess your aptitude for flying, maths, basic technical understanding, and you will have to do some group exercises which will suss out your english/communication abilities etc. The only problem is: its costs around £250... but that shouldn’t be too much of a problem for you considering your situation?
