@ificouldreturnit,
"I haven't got to learn that many new words in English by heart to get by," isn't grammatical.
"I hadn't got to learn English when I was a boy," can be more grammatically written as, "I hadn't gotten to learn English when I was a boy."
"I didn't have got to learn English when I was a boy," can be more grammatically written as, "I didn't get to learn English when I was a boy."
