AFAIK Marxism isn't about equal outcomes, but it is opposed to enforced classes. So a Marxist would likely argue you shouldn't have lower and advanced courses separate, but you'd still have one course with a distribution of grades. The teacher would just focus more on the kids that need more help to improve the mean of the distribution, where our current method would create unnatural multi-modal distributions
If you're opposed to Marxism you should also know "double-speak" comes from a book written in support of socialism[1]
I know they're not equal, but typically people lump them together and oppose both without knowing the differences, so I figured OP would like to know they're quoting a socialist to oppose Marxism, because they might actually really support socialism even if they oppose marxism. I guess I shouldn't have said "in support of socialism" and instead "by an author who hugely supported socialism", but I think it's fair to say his works were influenced and driven by his political beliefs since that's so much of the focus. It's not a book talking about how great socialism is, but it's also not at all a critique of socialism. It's just about totalitarianism, and people often use it to oppose socialism or marxism so wanted to throw this out for clarification
A classic example was Orwell in the Spanish civil war saying he was super against Stalinism specifically and also seemed to know that it was not at all communism, but overall he seemed to primarily like democratic socialism.
Maybe this is because I'm from the US but here most people think Stalinism==Communism==Socialism==Maoism, so I think it's important to point out differences

> This is different from Marxism which relies on a violent revolution
This is definitely not true so I wouldn't trust that source much. Some people think it's the only way but others don't
