This was question in test practicing creation of Question Tags. For answer I chose: "H'd better try harder, wouldn't he?" but test rejected this answer... I don't understand what is the rule here? My guess is that "H'd better try harder" = "He would better try harder, wouldn't he?" therefore answer was correct. Help???

Your guess is wrong. The 'd in He'd better try harder is short for He had better try harder not He would better try harder.

There is a phrase "had better." It means like "should."
It won't take time to look this up in a dictionary.
