Hi, I can’t decide between 2 A levels and I need help.

Hi, I am picking my a levels this year, and I cannot decide between two. I am going to pick 4, but the one I select as my 4th one has a low chance of being in a diferent block.

My choices so far are: Maths Physics Geography D/t (product design)

I can’t decide if I should put geography or product design 4th.

Could you guys assist me and give some general insight into the subject and which one is better?

Thank you.
