that's good to know.
I'm currently reading the pre course eBook. I'm getting there but it seems to assume a certain level of cellular function knowledge.
I covered it as a precursor to kicking off my degree many years ago but not to the level in the book!
Still, I'll not let it beat me. I read a chapter a day, re-read it the next day (to make sure it has sunk in) and then on to the next chapter...
I must say it has been very interesting so far. :)
