Geography A-level NEAWatch this thread
Do whatever’s going to be easiest to collect useable, relevant data and a range of media (maps, photographs etc..)
I loved my title (did it on organic soil content and infiltration) but whatever you choose is going to become less interesting as you get into the thick of the project and deadlines start approaching. Honestly making the topic as accessible as possible for yourself will give you the best possible chance of enjoying your NEA. Extra stress will deffo ruin it.
