How Did You Become Confident in English to Study a Master's Degree?

After graduating in high school I entered a bilingual program for my bachelor's degree so like half of my courses were taught in in English. The first time I took an English proficiency test I kind of like to study in Japan did not do that well enough to to do an exchange semester in Japan but I mean I had like 6.5 which takes a world it was the aisles I had like B2 level enough to go to university in some countries yeah in some countries but not in the UK though and then I I lived in Japan surrounded by non-fames speaking people and definitely I had to to be out there and communicate with everybody so yeah it was definitely another step towards confidence.
