A real future possibility
The first conditional often uses if + present simple, followed by will + base verb. Use it when the speaker treats the condition as a real possibility. The present tense in the if-clause can refer to the future.
If the workshop finishes early, we will visit the library. We will send the report if the data arrives today.
An imagined situation
The second conditional often uses if + past simple, followed by would + base verb. It presents an imagined or less likely situation in the present or future. The past form signals distance from reality; it does not necessarily describe past time. In formal hypothetical statements, were can be used with all subjects.
If I had more free time, I would join the debate club. If I were the course leader, I would offer a weekly question session.
Choose the meaning first
Both conditional patterns can be grammatical, but they communicate different views of the situation. If I get the grant presents the grant as a live possibility. If I got the grant places the speaker in an imagined scenario. In these standard patterns, put will or would in the result clause, not immediately after if.
Real possibility: If I receive an offer, I will reply this week. Imagined situation: If I received two offers, I would compare the course content.
