I wrote my Duolingo English test twice, I got the same 100 result, Should I try again or I should start looking for college for my masters.?

I scored similarly in my English test. In my experience, a score of 100 in the Duolingo English test is generally acceptable for most colleges, especially if your academic record and other parts of your application are strong. I would suggest starting to look for colleges and checking their specific language requirements.

Also, consider other factors like the course content, faculty, and research opportunities while choosing a college. Balancing your efforts between improving your score and finding the right college can be key. Best of luck!
