Talking about science, I was bad at maths, physics and chemistry, so I dropped the last two and took German instead. My brother was good at maths and gave me the necessary tutoring to scrape through my GCE O level.
These days though, I am renewing my interest in all sciences, and have found this book by evolutionary biologist Richard Dawkins to be a wonderful tool to reeducate myself. It is called 'The Greatest Show on Earth', and made me realise that the man is an excellent educator. At least I understand the periodic table now.
As a gardener, I'm taking a renewed interest in plant biology too. I think, in my case at least, hard science was very scary at school, and was taught with little patience for those of us who found it difficult. I was always OK at biology, perhaps because there's hardly any maths in it, or perhaps because we had a great teacher.
On the subject of French schools and business - yes, my Brother in Law is a teacher over there, and won't teach in the school system. He teaches English to adults instead. He and my sister are self-employed translators too, and the French business system drives them crazy. However, the high taxes do at least provide an excellent national health system which saved my sister's life when she had a double transplant. She is blind, and the provision and vet care of her guide dog is all free too.
