The problems of undergraduate schools do account for a large proportion in the second interview, especially in the second interview, which usually asks whether it is one or two, and the interview accounts for a large proportion.
According to your situation, it is very promising to be admitted to an ordinary master's degree of 2 1 1 or a relatively ordinary master's degree of 985.
Many schools are not satisfied, especially those with special degrees, so if you go in with a volunteer, the second interview will basically not be brushed.
I suggest you find some people who have been admitted before to inquire about the re-examination and start preparing for the initial examination as soon as possible.
High scores in the initial test can also leave a good impression on the interview teacher.
