Does this make sense and what does it mean?

そのあとで、日本語がとくいだことになったと思います。

Does this translate to: After that I think I became good at Japanese?

question
particle-こと
Is this a correct use of 〜ことになる?
No. If it's 日本語が得意{とくい} **な** ことになった, it means "I ended up being regarded to
be good at Japanese (against truth)", though.

answer
You could say:

日本語が得意になったと思います。

ことになる has a different meaning. According to "A Dictionary of Basic Japanese
Grammar", page 202: "An event takes place as if spontaneously, irrespective of
the speaker's volition."
