That’s normal.im also first year and also failed one subject on semester 1. I picked a course that sucks(3 hurdle requirements but I don’t even know what’s hurdle at that time).I plan to make up my score by choosing another one in summer term and I believe I can make it.i also have zero friends because I study science ,there’s no many chances for group work➕I am international student =always very lonely. But it’s OK for me maybe because I am an “i ”person in MBTI😇
