Had I been in that situation I think I would have retaken A levels.
Bit drastic and even now that option would be open to the OP. They could use their gift year to restart or finish this year and see if they would accept a transfer.
This is especially so because a mit circ claim can get dull and resitting shows a person dealing with the problem in another way. Assuming the results are obtained then it speaks for itself. All at the cost of a year.
All a bit twisty but nobody said we all had to follow the same path.
Agree the global politics module sounds a bit questionable.
@jess1558Assuming this is your first year then you should consider what you wish to do and go through the options.
Its better to equip yourself as best you can to improve your chances later on. You still have options now, even if they sound drastic. You may well be glad you took them later on down the line. So not underestimate how competitive it can be.
