I need to prepare for my German exam and there are 600 words that I should be familiar with. To obtain an A in this exam, I am required to recall at least 90% of these words correctly. Assuming that I can remember perfectly the words that I memorize, and assuming that my guesses for the other words contribute no correct answers, how many words must I learn to guarantee at least a 90% score on the exam?

Present the answer in LaTex format: \boxed{Your answer}
