Решение
Общий закон природы — Zero Conditional: when + Present Simple, Present Simple: freezes — turns.
Совет — Conditional II: if I were you, I would follow.
В условии had known (Past Perfect), значит Conditional III: would + have + V: wouldn't have taken.
I wish + Past Simple — сожаление о настоящем («жаль, что он редко звонит»): called.
If only + Past Perfect — сожаление о прошлом (деньги были, а сапоги не купил): had bought.
Unless = if not, после неё Present Simple, в главной части — will: studies — will fail.
