After completing a one-year master's, what will I learn in the remaining six months in UK?

There is no remaining six-month period after a standard one-year master's degree in the UK - the program is designed to be completed within 12 months, including both coursework and your dissertation or major project. Typically, you will study foundational modules in the first term, advanced modules in the second, and focus on your dissertation from spring to late summer. The schedule is intensive, so it's important to plan for a full-time commitment throughout the entire year.
