Inversion and conditionals
Look at these examples to see how we can create conditionals with inversion.
Should you have any questions, I will be happy to help.

Grammar explanation
We use conditionals to describe the result of a condition. Often, we use if to introduce the condition (e.g. If you feel hot, …) and the main clause to give the result (... feel free to switch on the aircon).
Conditional sentences can also be created without if, using inversion. Inversion means reversing (inverting) the normal subject–verb word order in a sentence. This makes the sentence more formal.
Three types of conditionals can be formed using inversion: first, second and third conditionals.
First conditional
We use the first conditional to talk about future situations we believe are possible.
Marker pens are in the cupboard if you ever need one.
If a customer wishes to cancel their booking, they should notify us within seven days.
To invert first conditional sentences, we replace if with the auxiliary verb should and change the verb into the infinitive. This makes the situation seem a little less likely. It is often used to make a polite request or offer.

Should a customer wish to cancel their booking, they should notify us within seven days.
Second conditional
We use the second conditional to talk about situations that we consider unlikely or impossible in reality.
How would the environment be affected if everyone reduced their meat consumption?
If the Sun disappeared, Earth would no longer be able to support life.
To invert second conditional sentences, we replace if with were and change the verb form to to + infinitive.
How would the environment be affected were everyone to reduce their meat consumption?
Were the Sun to disappear, Earth would no longer be able to support life.
Note that if a second conditional sentence uses the verb be, we don't need the infinitive for the inverted version. We just replace the existing form of be with were, and invert the subject and verb.
If California were a country, it would be one of the world's largest economies.
Were California a country, it would be one of the world's largest economies.
Third conditional
The third conditional is used to imagine a change in a past situation and how things would have been different in the past as a result.
If we had lost that match, it would've been a disaster.
We would have fixed that problem by now if we'd known about it earlier.
To invert third conditional sentences, we remove if and invert the subject and the auxiliary verb had.
Had we lost that match, it would've been a disaster.
We would have fixed that problem by now had we known about it earlier.
Negative inverted conditionals
To make negative inverted conditionals, we put not after the subject.
Should you not consent to sharing this information, you may inform our company at any time. (= If you don't consent …)
Were I not good at maths, I'd find this homework very challenging. (= If I wasn't good at maths …)
Had I not been busy this morning, I would have attended the meeting. (= If I hadn't been busy …)

If I am accepted into the training programme, I will study extremely hard
This is a sentence in first conditional, therefore for inversion we use "SHOULD", not "WERE" ("were" is for second conditional inversion).
The answer, then, is
Should I be accepted into the training programme, I will study extremely hard.
We do not change anything in the main/result clause, which is why it doesn't offer the option to change will to would.
Hope this helped.
Cheers
That's right, Lilly Bee!
Thank you.
But the problem is the inversion so done with 'should' and the second conditional apparently have the same meaning. Won't you agree?

Hello Peter and Comet,
Yes, as Peter says, the sentence upon inversion will be "Should I be accepted into the training programme, I will study extremely hard."
But, I don't know what the difference is between a conditional sentence having 'should' in the condition clause and the second conditional sentence, as both refer to a situation which is unlikely to happen.
Could you just explain?

Hello Shetu Yogme,
Conditionals with should are alternatives to present/future likely conditionals, sometimes called type 1:
The form with should has the meaning 'if this happens to me'. In other words, they add a sense that the condition is (a) a little less expected and (b) happening to the speaker without the speaker's control.
A famous example can be found in the poem 'The Soldier' by Rupert Brooke:
Here, the use of should adds a certain fatalism to the sense: Brooke has no control over his fate.

Hello
Is there any difference between ''If it were possible...'' and ''If it was possible...'' ?
When do you use each?
Thank you
Hello danielcanton,
If it were is an example of the subjunctive in English and it is a form which is gradually disappearing. In modern English you can hear both forms are used and there is no difference in meaning.
If it were used to be seen as the only correct option and if it was as incorrect but this has changed over time. However, I would say that if it was is certainly less formal and some people (grammatical traditionalists, let's say) might consider it non-standard so you are probably safer sticking with if it were to be on the safe side.

Could anyone explain why to use "for" in these conditional sentences: "Were it not for school being compulsory,..." and "Had it not been for the gorgeous weather,…"? Thank you.
Hello LizaEva,
We use 'for' in this way in conditional sentences:
Your examples are conditional sentences using inversion. As to why we have this form, I don't know what the origin is. I can tell you another form of it using 'but', however, which you can come across in more formal contexts:
