It depends (if I'm wrong, teachers, please correct me)

If you use :
1) I will go to school at 6 o'clock tomorrow it means that you have decided to go there at 6 o'clock (but maybe you go there usually at 7)
example :
Sue: Are you going to school tomorrow?
You : Well... Yes, but I think I'll be there at 6 o'clock (but Sue and you usually go to school at 7 o'clock)
2) I think it's incorrect. You can't say "I go to school tomorrow" it doesn't make any sense ( "I go to school at 6 o'clock everyday" would be correct, for instance)
3) I'm going (to go) to school at 6 o'clock tomorrow. would be correct, but it indicates that it's something temporary (for instance you must go there at 6 o'clock to help your friend to do their homework, but usually you go to school at 7 o'clock)

Hi,

Just one other point. There is an instance when we can use the Present Simple with a future meaning. That is when we want to refer to some fixed future event that is often in a plan or a schedule as in:

The President arrives at the airport at 7 am tomorrow.

You might like to look at some material I've written for the site on ways of expressing the future:

Future Tense or "Jealousy"

Present simple is almost the same as GOING TO but it's not quite as personal.
what does " it's not quite as personal" mean?
