Use of aux. "be" with "got" for passive?

Someone got full marks in the exam.

Is it possible to change its voice to passive using got as follows?

Full marks were got by someone.

Why or why not?

Solution 1:

There's a difference between "past tense" and "past participle". When you're forming the passive voice, you use the past participle.

In British English, the past tense and past participle are the same for "to get".

Full marks were got by someone.

However, in American English, the past participle is "gotten".

Full marks were gotten by someone.

Though this is proper, it still sounds a little awkward. If you insist on using the passive voice, you might use a synonym.

Full marks were achieved by someone.

or...

Full marks were acquired by someone.
