At the first round of the series at Manfeild in October, the 24-year-old overcame last-minute power steering issues to qualify for the top 32 before proving his potential by running established series star Woolhouse close in van Gisbergen's first battle.
"The more I do the more confident I get but I've still only done one proper battle [against Woolhouse at Manfeild]," said van Gisbergen.
"The single car stuff is good, but I've still got a lot to learn as far as the battles are concerned."
