"Yo creo que esta clase es muy dura."

Translation: I think that this class is very hard.

[JDreamz]

In spanish we never say : creo que esta clase es muy dura.
we say : creo que esta clase es muy difícil.

[Kenny977777]

Wouldn't dificil be more appropriate in this sentence?

See definition #5.

Personally i would say
I think that this class is very hard

[doublelingot]

I think/believe (that) this class/course is very/really hard.

[MasterYods]

I guess this means that 'hard' has the same physical and metaphorical meanings in Spanish as in English.

[camwillits]

Yep!

[Donald798622]

Yes. Curious that.

[Milo212113]

It needs to add the word that in English.

[rowith]

"Que" is required in this sentence. In translating to English, "que" means "that" but can be omited.

[Hazithzantos]

I chose the more direct translation but, would it accept "I think this class is very hard"? Omitting the "that" which colloquially is unnecessary.

[1e7nx0WG]

Yes, it would accept "I think this class is very hard".

[Baha2557]

Personally, i would omit the "that" used in this translation

[ArgleBargle1961]

According to spanishdict.com, this class can be considered "dim-witted." That is, dim, boring, dull. Yes, I already submitted "my answer should be right."

[BrianTice]

I see creo and look for "I believe;" "I think" is pienso.

[Estaban429727]

Just my way of looking at them. Creer is believing with faith and thinking based on that faith while pensar is thinking using logic. No guarantee that's accurate or even logical, but it is the way I have sorted out this two for one word since I started French back in the 60s

[peejayking]

i think this is a very hard class..???? and why not..!
