Cambridge director of rugby Bob Crooks claims his side took a step forward with the 51-28 win at Rosslyn Park.
The result ended a three-game losing run for Cambridge in National League One and Crooks was pleased to see his young outfit play with confidence.
"We've changed, we've grown a little with regards to our decision making on an offload or taking an extra phase," he told BBC Radio Cambridgeshire.
"We really did show in our second half performance that we've grown."
Cambridge, who are third in the table and 22 points behind leaders London Scottish, have just six games of the season remaining.
Crooks is challenging his men to show their mettle against some of the division's strugglers, starting with Redruth on Saturday.
"Now what we need to do is roll this out next week and the week after when we start playing against teams fighting relegation," he said.
"Because teams like the Redruths and Otleys will fight harder and we've got to be better against them."
