If the answers are truly distributed randomly, then any random selection of letters would produce roughly the same score.
Whether they’re actually random or not would depend on who wrote the test.
Whether you’d get a better score by guessing or not would depend on the way the test is graded - many standardized tests subtract 1/4th of a point for wrong answers so that a random guesser will get a zero.

That's a pretty big "if", though. A lot of tests are written by hand and bias away from long answer streaks and first/last answer choices.

Yes--back when I was in high school in the late 80s, one of my teachers also taught a SAT prep class, and at the time they were teaching a strategy where if you had no idea and just had to guess, then avoid ACEs and doubles. A was too easy, E too hard, C too obvious, and test creators don't like answer streaks. I would assume test creation methodology has changed for the SAT in 30 years, but it still may be helpful for any human-created multiple choice tests out there.

It would surprise me if that were accurate for the SAT even back then.

I didn't take the class, it was just a quick summary he gave of part of his class, but if humans are selecting the answers, or even just reviewing and editing the answers, there is going to be some sort of bias--"that's too many Cs in a row," or "there's too many As in this section." Whether or not one specific "SAT tips!" advice or another was actually better, I don't know.
