Choosing well
Whichever computer science topic you choose, narrow the population, time frame and geography before you write the proposal. A tight scope is easier to defend at viva than a broad one. Use our /research-methods pages to shape a realistic methodology, and see /services/assignment-help if you need a specialist to co-write.
