Please need help with a few sentences

Hi teachers,
Could you help me with these sentences? They are for English classes, for a company where I'm going to teach English. They want them in English, so it is hard for me to translate them from Spanish to English. That's why I've asked for help.

Which one is better for classes with students?
a) Face to face hours.
b) Presential hours.

Which one is better for classes where I give the students some pages for homework? I do have to specify 'hours', some kind of legal matter.
a) Distant hours.
b) Homework hours.

Are these appropriate titles?
a) Beginners English Course.
b) Intermediate English Course.

What about this one? It is for people who don't know about the English language yet. Can it be better?
Objectives: Acquire English knowledge.
This one is for people who already have an intermediate level of English. Can it be better?
Objectives: Expand English knowledge.
Thanks in advance
