I have 4 questions about this sentence below,
“I wish I was a doctor who could cure all the cancers.”
The first is if it is a grammatically correct sentence.
The second question is if it is the best choice to use "was" instead of "could be" or "would be".
The third is if it is OK to say "...who can cure all the cancers" in this sentence.
The fourth is if I can use "hope" instead of "wish" here.
