Present situations

• If I were you, I would marry her.
• I wish I were you.
• If we were to do that, we would be rich.
• Were she my sister, I would not let her go.
• If I didn't have to prepare for the exam, I would definitely go.
• If it weren't for you, I would not be here.
  

Past situations

• If I had been to the class, I would have (would've) known that.
• If he had left the pub earlier, he would have met you.
  
• I wish I had worked harder.
• She missed the unborn children that would have made her complete.

Mixed

• If you had accepted the job at that time, you would be a manager by now.
• If I weren't going abroad next year, I would have accepted the job offer last year. (I would accept the job now)
• If it weren't for you, I wouldn't have gone through all these trouble.
