I've gotten to the boss battle with Zant. I've been trying to get past the last part outside of the s.Enterance of Castle Town, but can't. What do I do?

That depends. If he's in the form in which he has two swords and just goes crazy, I used the Secret Skills Shield Attack and Back Slice to smack him around. The only attack you really need to watch out for is the one where he spins around a bunch, try to roll or jump away from that one (this is all from memory, it's been a couple of months since I did this).

When he does his spin attack keep blocking it with your shield until he gets tired. Make sure you don't get knocked into the walls as they can hurt you.

After he has finished his spin move he will be tired, either use the jump strike on him or if you don't have that a normal spin attack will do or normal four hit combo.

When he uses his vertical slice attacks dodge round him and hack at him using the tactics Mcfugg sugested.
