It uses the very common pattern 无论 … 都 …, which means no matter …, … or regardless of …, ….

So the sentence is structured like this:

无论 + 会员什么时候来， 都 + 可以看课程表。

That means the result in the second part is true in every case mentioned in the first part.

A simple comparison:

• 无论你几点来，都可以进去。
  No matter what time you come, you can go in.

• 无论会员什么时候来，都可以看课程表。
  No matter when members come, they can look at the course schedule.

In this kind of sentence, 都 is a key part of the 无论 … 都 … pattern. It shows that the main statement applies in every case.

So here, 都 does not just mean all in the simple vocabulary sense. It helps express in all cases / regardless / no matter what.

If you remove 都, the sentence sounds incomplete or unnatural:

• Natural: 无论会员什么时候来，都可以看课程表。
• Less natural: 无论会员什么时候来，可以看课程表。

So for learners, it is best to remember 无论 and 都 as a pair.

Because Chinese question words can also be used in non-question structures.

Normally:

• 会员什么时候来？
  When do members come?

But after 无论, 什么时候 means something like whenever / no matter when:

• 无论会员什么时候来
  No matter when members come

This is very common in Chinese. Other examples:

• 无论谁来，都欢迎。
  No matter who comes, they are welcome.

• 无论你去哪儿，我都支持你。
  No matter where you go, I support you.

So 什么时候 is still a question-word form, but the whole sentence is not a question.

会员 is the subject of the clause 会员什么时候来.

It means member or members, depending on context. Chinese nouns often do not show singular/plural the way English nouns do.

So 会员 can be understood as:

• a member
• members
• the member(s)

In this sentence, English will usually translate it as members, because the meaning is generic.

Because 们 is not required for generic plural nouns in Chinese.

Chinese often uses a bare noun when speaking generally:

• 会员可以看课程表。
  Members can look at the course schedule.

Using 会员们 would sound more like you are talking about a specific group of members already known in the situation. It can add emphasis, but it is not the normal choice for a general statement like this.

So:

• 会员 = natural, general
• 会员们 = possible in some contexts, but more specific or emphatic

Because Chinese time words usually do not need a preposition like at or on.

In English, we say:

• at what time
• when

In Chinese, a time expression can often go directly before the verb:

• 会员明天来。
  Members come tomorrow.

• 会员什么时候来？
  When do members come?

So 什么时候 can directly function as the time expression, and 在什么时候来 would usually sound unnecessary or awkward here.

Chinese usually leaves question words in the same place where the answer would go. This is often called question word in place.

For example:

• Statement: 会员下午来。
  Members come in the afternoon.

• Question: 会员什么时候来？
  When do members come?

The answer slot is where 下午 goes, so 什么时候 goes in that same position.

Then the whole clause 会员什么时候来 becomes the first part of the larger sentence:

• 无论会员什么时候来，都可以看课程表。

So the word order is very normal Chinese word order.

Here 来 means come or arrive.

It refers to the members’ coming to the place or situation being discussed. In natural English, depending on context, you might translate it as:

• come
• arrive
• show up

So 会员什么时候来 can mean:

• when members come
• when members arrive

Both 可以 and 能 can sometimes be translated as can, but they are not exactly the same.

In this sentence, 可以 is natural because it suggests permission, availability, or it is allowed/possible to do so.

• 都可以看课程表
  can all look at the schedule / are allowed to look at the schedule / may look at the schedule

If you used 能, it would more strongly suggest ability or practical possibility.

So:

• 可以 = allowed, okay to, available to
• 能 = able to, capable of

In this context, 可以 is the better choice because the sentence is about what members are allowed or able to access whenever they come.

Yes, it is natural.

In Chinese, 看 is used very broadly. It can mean:

• look at
• read
• watch
• check
• consult

So 看课程表 does not just mean physically stare at it. It can mean check the course schedule or look over the timetable.

Other possible ways to say something similar are:

• 查看课程表 — more formal, more like check/view the schedule
• 看一下课程表 — softer, more conversational

But 看课程表 is perfectly normal everyday Chinese.

Yes, in many cases it can.

You could say:

• 不管会员什么时候来，都可以看课程表。

This has almost the same meaning.

A useful rule of thumb:

• 无论 = a bit more formal or written
• 不管 = very common in speech, slightly more conversational

Both are very common, and both usually work with 都 in this kind of sentence.

Yes, it is helpful and normally recommended in writing.

The comma separates:

1. the condition/whatever-case part
   无论会员什么时候来
2. the main result part
   都可以看课程表

So the comma makes the structure easier to read:

• 无论会员什么时候来，都可以看课程表。

In speech, you would usually make a small pause there too. Even if the comma were omitted in casual writing, the meaning would still be clear, but using it is better.

Yes.

Because 会员 does not show number by itself, the Chinese can be interpreted generically. English has to choose singular or plural, but Chinese often leaves that open.

So depending on context, it could be understood as:

• Whenever a member comes, they can look at the course schedule.
• Whenever members come, they can look at the course schedule.

In many textbook-style translations, members sounds more natural, but both are possible in principle.
