I'm not doing history so it's hard to judge. However from my experience I can make a few comments about certain subjects.

Subjects that have a large gap between SL and HL content:
Physics
Mathematics
Chemistry
Biology
All Languages

Small gap between SL and HL content:
Economics
Geography
English

Subjects that are hard conceptually:
HL maths
HL Physics

Subjects that are hard due to the sheer content you need to remember:
Economics
Biology
History
HL Chemistry (SL chem is easy)


If you do HL Physics, SL Chemistry will be a breeze due to alot of the concepts already being covered in physics.
thanks a lot you are really helpful!!
taking history HL and physics SL finally :)
hope it will help
