My son did his Extended Project Qualification (EPQ) in 2018, at Hills Road Sixth Form College, Cambridge, and it was really interesting to watch. For something worth just half an A-level (and in reality when it comes to university applications, worth nothing), it required an astonishing amount of work. For busy sixth-formers to find the time or the motivation requires some dedication. That said, the EPQ is a good introduction to doing a properly planned and structured research project, so I encouraged my son to take the trouble. He did so, and his project was eventually marked 100% (A*) in 2019.
