You become a doctor. There are no courses. Anesthesiologists are full doctors with specialised training.
It doesn't matter what you take in high school, medical schools won't look at that transcript. You take sciences (chemistry, bio, physics), maths and English. Then you apply to university for a Bachelor's degree in the sciences.
Medical schools will look at your undergrad transcripts so you need to excel. You need to be top of your class just to be considered. You need your 4 year Bachelor's High score on the MCAT If selected you take 4 years of medical school.
Then you do your residency. Another 1 to 2 years Once you pass that, you are a doctor. If you are good enough, you can move on to specialty training.
Expect to spend a few more years training to be an anesthesiologist.
Don't think about the future yet,, just think about the present prob that you are facing,,, I like to recommend you to take a test 1st.. www.16personalities.com/free-personalit... just think about urself 1st the the future.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
