I tell my friend why I'm leaving today instead of September 26th. I say:<br/><br/>If I go back on the 26th, I'll be flying straight to school, because it starts the next day. <br/><br/>Or<br/><br/>If I went back on the 26th, I'd be flying straight to school, because it starts the next day. <br/><br/>What's the difference and which one is the more correct usage?<br/><br/>Thanks!
