Thank you very much for your reply, which means a lot to me. But I have another question. Is TOEFL score a very important part of the application? Should I spend a lot of time reaching the TOEFL level of 110 (my current score of 100 just meets the minimum / recommended requirements of all schools I want to apply for.) In fact, some people told me that I need a TOEFL score of 110 to be more likely to be admitted. However, someone told me that after the TOEFL score met the requirements, higher scores did not have a significant impact.
