Create a directory under your name
in the course directory at /p/edu/mat-1.174/k99/oppilaat/
mkdir my-name
cd my-name
mkdir h1 # for "harjoitus 1"
chmod -R go-rx h1 # Deny access
After the Thursday-session or whatever is decided as the dead-line,
give read permission:
chmod -R go+rx h1

in HTML form just by EXPORT HTML in the FILE-menu.
