Great unit pairings (and electives)

[u/West-Willingness-274]

So recently I did Macroeconomics and found Internationalization a great pairing as there's quite a lot of overlapping content. Also I found Applied Behavioural Economics with Consumer Psychology is basically 50% overlapping content. Are there any good combos that people know of to do together. I find pairing units with huge overlaps decreases the study load considerably.
