Any Geography Exam boards just exam based?

There are all based on the old spec, since the new spec will not be out for another year meaning you'll still be doing the old style exams for Geog.

AQA - All exam based but AS Unit 2 is an exam on fieldwork (however this is apparently 'generic' ) A2 Unit 4 gives two options one field work evaluation and one 'geographical issues evaluation'. So I guess you could do this board and take option B for A2 Unit 4.

WJEC - All exams, AS G1 and G2 require fieldwork knowledge but again this is generic. A2 G4 is just about sustainability. Just do watch out for A2 G3, which is an exam however you have to carry out research based on a theme for it. I'd say maybe don't do this board as Unit G3 is just going to be a bit of a hassle.

Edexcel - All exams again, AS unit 2 requires investigation data. I assume it accepts online research etc rather than fieldwork by the looks of it. Possibly consider this board or AQA.

OCR - Requires investigation/fieldwork for Unit 4, better to find alternative board. Would be fine for AS only, however.

CIE International AS/A Level - I think this might be the best board if not Edexcel or AQA, as AS is 1 exam all based on knowledge and no fieldwork what so ever. A2 Unit 2 and Unit 3 are on Physical and Human geography and have very minimal fieldwork questions, looks pretty passable without barely any fieldwork knowledge.

Summarised:
AQA - Bit of fieldwork knowledge for AS, otherwise this board is fine
WJEC - Loads of fieldwork knowledge, possible but a hassle so a no go
Edexcel - Look more at the spec but this board would be fine
OCR - AS only
CIE - Recommended tbh
