Martin Allen challenged Barnet for one last win after a 4-0 victory over AFC Wimbledon put them in the box seat to avoid relegation.
The Bees took the lead through Ricky Holmes on 33 minutes and he went on to set up second-half goals for Sam Deering and Ben May.
Mark Hughes added a fourth goal in stoppage time but with fellow strugglers Hereford pulling off a shock win at Crawley the relegation battle will go down to the final day.
"I patted them all on the back, shook them all by the hand and then told them we've got another week to go," said Allen. "Well done to them all they played really well. I enjoyed watching them play. I thought they showed great courage to take on that last game at home, they were playing under a bit of pressure and I thought they did really well.
"We've got one more tester next week because Hereford had a great result. So on we go again to Monday. We played some good football and the supporters really got behind the players and that's really key to the unity that we've urged from everybody.
"I was looking forward to seeing the players play well. This is not about me, this is about the players and this football club.
It's nothing to do with me. It's about getting the players to try to play well and giving the supporters something to see on the pitch. It was good for everybody. But we've got one more challenge next week."
