You could ask your instructor what you could be doing in your time between lessons. Set aside time every day (or as many days of the week as you can spare the time). Just 30 minutes is enough. Even 20 minutes. Block the time in your calendar. I’m a fan of studying vocabulary and verbs when studying independently. If you are at intermediate level, add idioms. This way when you’re with a human, you have more language to draw on for practicing language and learning usage and grammar. You can also use some of those spots for Community Tutor practice.

“as long as it isn’t raining” is in the current moment. “as long as it doesn’t rain” is about the future. You are hoping that at some point in the future it doesn’t rain.

Question 2 is A. This is the same in a lot of the world (the number of months in a year is the same at least) Question 3 is C. This is something you just have to memorize if your country doesn’t have 4 seasons. Question 4 is C but to be honest, in spoken English (at least in the US), you will also often hear A used. Question 5 is A. The first person asks if you “can” skate, meaning “are you capable of skating” or “are you able to skate”. The responses are: A-can (I am able to), B-do (I skate - but grammatically this would be incorrect to use) C-will (I am going to skate—which does not answer the question)

Actually, I have lived in multiple places in the US and many schools do not have a theater as you describe although most have some kind of elevated “stage” somewhere in the school for presentations and assemblies. Sometimes this is in a “multi-purpose” room that serves as a gym, a cafeteria and an assembly place—but does not always have a curtain. Not all schools do theater/plays, either. That stage is used for many other things—so its existence is not tied to theater activities.

I’m not sure there’s a great way to say this without sounding odd but I would change to “it can fit…” as opposed to “we can fit…” because it is the elevator that is fitting the people. I might say “No, there’s enough room for us.” Or “No, there’s at least enough room for us.”

Agreeing with Jonathan that US vs British applies here in terms of "takeout" vs. "takeaway" and there would not be "a" with either. Also agreeing that if you were placing the order AT the location and waiting for it, it would be EITHER "in a bar close to the office" or "from A bar close to the office". Either way, it's "a bar" If you placed the order from a location other than that bar and had to go to get it, it would be "from a bar close to the office".

"at Julia's house" (the " 's " shows ownership/possession) "when I bake" ("some food" is implied because this is what the oven is usually used for--if you were using the oven for something that is not typical, then it would be appropriate to specify. For example "when I bake my clay") "ten minutes before the time for her job interview" - while this is understandable and correct, it's not spoken this way. Some options are: "ten minutes before her (job) interview." "job" is implied here as you are usually interviewing for a job but you could put it in as sometimes you interview for an internship or a volunteer position. "time" is also implied here as interviews are always at a specific time "ten minutes early for/to her (job) interview." "early" + "for"/"to" If she is arriving 10 minutes before the interview, she is early. But because "early" comes before the action/item for which she is arriving, you have to explain what she is early FOR, so we say "early for... (thing they are arriving early for/to)".
