What's your choice and why?

Which one would you like to be in?
1. Being the last student in A class.
2. Being the first student in E class.

Which one would you like to be in?
A. You earn 10k and your neighbour earns 5k.
B. You earn 50k and your neighbour earns 100k.

My choise is 1, B.

1 Because, being in A class, I have the best teachers and more chances for enrichment. I wouldn't be a public enemy among my classmates.

B Because the difference is big enough that I wouldn't be bothered to think about it. Although on the second thought, the 50k is actually more than 10k.
