IndyCar rookie Marcus Armstrong aims to accelerate his knowledge when it comes to street circuits in America

The 23-year-old has impressed in his rookie season, starting eight races and finishing in the top-10 on four occasions.

But Armstrong wants to get up to speed with the courses during practice and qualifying so he's not behind on race day.



Armstrong will start from 16th for tomorrow's race in Nashville - which starts at 5am.

Countryman Scott McLaughlin is on pole position - with Scott Dixon starting 12th.
