So what the sentence is saying is that if I study now(which is the condition) I will pass the exam in the future(result). It uses the following structure:

if/when + simple present, will + infinitive verb

Below are some more examples,

☁ If it doesn't rain tomorrow, we'll go to the beach.
⚽ Arsenal will be top of the league if they win.
💼 When I finish work, I'll call you.

2⃣ So then what are second conditional sentences? They are used to imagine present or future situations that are impossible or unlikely in reality.

📚 If I studied, I would pass the exam.

So what this sentence is saying is that, if I was a person who generally always studied, I would pass the exam. This sounds like it didn’t really happen to the subject and thus he is making this statement.

The structure used in second conditional sentences are

If + Past simple, would + infinitive verb

Let’s look at a few other examples of second conditional sentences,
🌸 If we had a garden, we could have a cat.
💸 If I won a lot of money, I'd buy a big house in the country.
👍 I wouldn't worry if I were you.

3⃣ The third conditional is used to imagine a different past. We imagine a change in a past situation and the different result of that change.

📚 If I had studied, I would have passed the exam.

So here the subject wished he had studied in the past so that he could have passed the exam today.

The structure used in second conditional sentences are,
If + Past perfect, would have + Past Participle


Let us look at a few examples.

🎂 I would have been happy if you had called me on my birthday.
📱 We wouldn't have got lost if my phone hadn't run out of battery.
🏥 If I'd known you were in hospital, I'd have visited you.

Try to form your own conditional sentences from what we have learnt today,

(if/when + simple present, will + infinitive verb)

2nd conditional
If I finished work earlier, __. (fill in the blank)
(If + Past simple, would + infinitive verb)

3rd conditional
If I had __, _____. (fill in the blank)
(If + Past perfect, would have + Past Participle)

That brings us to the end of conditional sentences. you can find this and previous lessons in our study room. See you next time.
