How do you change gear smoothly?

I'm learning how to drive but find it really difficult to change gear smoothly. My instructor explains it as a swapping of the feet. So I take my foot off the gas and go down on the clutch, change gear and then take the clutch to the biting point quickly and then go back down on the gas and slowly bring up the rest of the clutch from the biting point. But each time i do this there is a small bump feeling and it annoys me. If i try to do it as a slow swapping of the feet as my instructor explains it seems to take too long and I lose the momentum. Please help me. Sorry if this is confusing. How do you change gear smoothly?
Think of the gas and clutch as a teter-toter so when the clutch goes down the gas comes up to stop and the other way to go.
