Hello, everyone.
I have a question of tense in when-clause.
Suppose Tom is a sophomore now. He used to plan to work in America after graduation.
If I want to describe that with when-clause, which is right, 'Tom planned to work in America when he
finished college' or '...when he
finishes college' or '...when he
will finish college'?
Please give me some detailed explanation about concerned grammar rules if convenient. Those tenses really confuse me.
Thanks in advance.
