Going to a diffrent university after undergraduate degree? 10 POINTS AWARDED IM DESPERATE?

You do not have to go to the same school for bachelor's and master's. You should research schools that have master's programs suited to you and to what you want to do; you might not find that UCL offers a master's in your program or that its program is not suited to you. You may apply for admission into a master's program during your last year in school. Make sure you check the deadlines for admission into the master's programs at specific schools.
