Если хочешь отвечать точнее, сначала выслушай вопрос до конца.

In Russian, the subject pronoun is often omitted when it is obvious from the verb ending.

• хочешь = you want
• The ending -ешь already shows that the subject is ты

So Если хочешь... naturally means If you want... or, in context, If you want to...

Including ты is possible, but it usually adds emphasis or contrast:

• Если ты хочешь отвечать точнее... = If you want to answer more precisely...

Without emphasis, leaving ты out sounds more natural.

Russian often uses the present tense after если (if) when talking about a real or likely condition, just like English can do:

• If you want to answer more precisely, ...

This is not a past or hypothetical situation. It is a general condition: whenever this condition is true, the advice applies.

So:

• Если хочешь... = If you want...
• not necessarily If you will want...

This is normal Russian usage.

This is about aspect.

• отвечать = imperfective
• ответить = perfective

After хотеть (to want), Russian often uses the infinitive that matches the general meaning.

Here, хочешь отвечать точнее means if you want to answer more accurately / be answering more precisely in a general sense. It focuses on the manner or quality of answering, not on one single completed answer.

If you said хочешь ответить точнее, it would sound more like:

• if you want to give a more precise answer
• possibly in one specific instance

So отвечать fits better for general advice.

Точнее is the comparative form of точно (accurately, precisely) or related to точный (precise, accurate).

So:

• точно = precisely / accurately
• точнее = more precisely / more accurately

In this sentence, точнее functions like an adverb modifying отвечать:

• отвечать точнее = to answer more precisely

Russian often uses this short comparative form very naturally, where English might use more + adverb.

Yes, you could. Both are understandable:

• отвечать точнее
• отвечать более точно

But точнее is shorter and more natural in everyday speech. Russian often prefers the simple comparative form when possible.

So in this sentence, точнее sounds better and more idiomatic.

Because Если хочешь отвечать точнее is a subordinate if-clause, and Russian separates it from the main clause with a comma.

Structure:

• Если хочешь отвечать точнее, = subordinate clause
• сначала выслушай вопрос до конца. = main clause

This comma is required in standard Russian punctuation.

Сначала means first, at first, or before anything else.

Here it tells you the order of actions:

1. выслушай вопрос до конца = listen to the question all the way through
2. then answer

So сначала emphasizes: do this first before answering.

This is another aspect question.

• слушать / слушай = to listen / listen
• выслушать / выслушай = to listen through, hear out, listen until the end

In this sentence, the speaker does not mean just listen in a general ongoing sense. They mean:

• hear the whole question out
• listen to it completely before answering

That is why выслушай is used. It is perfective and expresses a complete action.

So:

• слушай вопрос = listen to the question
• выслушай вопрос до конца = listen to the question all the way to the end / hear it out

Because вопрос is the direct object of выслушай.

• выслушай что? → вопрос

Since вопрос is an inanimate masculine noun, its accusative singular form is the same as the nominative singular form:

• nominative: вопрос
• accusative: вопрос

So the form does not change.

The preposition до requires the genitive case.

• конец = end
• genitive singular: конца

So:

• до конца = to the end / until the end

This is a very common expression in Russian:

• читать до конца = read to the end
• смотреть до конца = watch to the end
• выслушать до конца = listen to the end / hear out fully

Not exactly as one fixed chunk by itself, but выслушать что-то до конца is a very common pattern.

Examples:

• выслушать рассказ до конца = hear the story out to the end
• выслушать объяснение до конца = listen to the explanation to the end
• выслушать вопрос до конца = hear the question out fully

So the important pattern is:

• выслушать + object + до конца

Yes. Russian word order is flexible, though some versions sound more natural than others.

The given sentence:

• Если хочешь отвечать точнее, сначала выслушай вопрос до конца.

is clear and natural.

Other possible variants include:

• Если хочешь отвечать точнее, выслушай сначала вопрос до конца.
• Сначала выслушай вопрос до конца, если хочешь отвечать точнее.

The original word order is good because it presents:

1. the condition
2. then the advice
3. with сначала placed prominently near the command

That makes the sentence easy to follow and stylistically smooth.
