I know this is subject to opinion and it 'depends on what you like best', but which history course sounds more interesting to you at A-Level?
Pathway 1: World History, you will be studying topics including Russia, 1917–91, from Lenin to Yeltsin; Mao's China 1949–76; Protest, Agitation and Parliamentary reform in Britain 1780 – 1928; and historical interpretations.
In Pathway 2: European History, you will be studying topics including Britain 1625-1701 - conflict, revolution and settlement; France in Revolution, 1774-99; Germany 1871-1990, united, divided, reunited; and historical interpretations. Significant changes mean that History A Level is now a linear qualification, with all assessments at the end of the two-year course.
Personally, pathway 1 sounds more interesting to me.
I'd go for Pathway 2 myself, but that's only because that's completely personal preference.
