"I can't attend the art class tomorrow."

Translation: 我明天不能上美术课。

[gliyj]

I this case, I think 我明天不能参加美术课 works too, if a bit awkward.

[AmitChopra9]

Would this be correct?"我不能上明天的美术课"

[Zukus]

It has the same meaning but is syntactically different. That would be more like "I can't attend tomorrow's art class"

[ktdilsiz]

我明天不能参加美术课？ would this be okay? Could someone native or fluent confirm?

[Zukus]

參加 is more like participate than attend

[wxf163c]

可以这么说，没问题。

[RobinThor]

what about 可以 instead of 能?

[WoyenSan]

Use 可以 if you the situation is you are not accepted to the class or something is preventing you to attend your class

[csboling]

Is it incorrect or awkward to use 来 or 回 instead of 上 here? Neither is accepted.
