Is it easier to get a 4 in foundation French or a 4 in higher French? (edexcel gcse)

Just asking because I just want to pass and I might have an opportunity to move down to foundation tier; but I don't know which is easier. Higher French is obviously harder but you need much less marks whereas in foundation you need quite a lot of marks. (btw I am terrible at French: it is by far my worst subject)

Any help will be greatly appreciated, thank you very much.

The tiers are structured so that, for the grades which overlap both tiers, a given candidate should achieve the same grade regardless of whether they took lower tier or higher tier.
So, for a grade 4, you would have no advantage in taking the lower or higher tier papers.
