Long story short I'm a American dreamer (a immigrant brought to the USA as a child but is illegal) and recently returned to my home country and not knowing the language here have had a hard time at school I am now 22 and think I can finally get somewhere I just need to teach my self Biology and Chemistry (Childhood dream was to be a biologist of some sorts) but I don't know where to start.
Can anyone recommend and books how how I should start my studying? I need to learn this stuff to be able to get into a university here. I wan't to start from the start and work my way up to University level.
Any sort of help would be greatly appreciated
Thank you in advance
Edit: TLDR: Basically I'm asking how I can home school my self to learn Biology and Chemistry to be able to get into a University and learn Biology and Chemistry on a University degree.
