Hello, this is Weekend Coding.
I looked into it after receiving feedback that there was an issue with the mock exam section’s compressed file.
On macOS, the archive was extracted normally, but an error occurred on Windows.
Upon checking, the PDF files inside the archive are normal, but it was confirmed that an error occurs when Windows interprets the file names. (The UTF-8 flag for file name encoding is disabled.)
I have recompressed and uploaded everything using a different method, so please check it.
Wishing you success.
