First find the total number of zits in Mr. Jones' class: 6 zits/kid * 32 kids = <<6*32=192>>192 zits
Then find the total number of zits in Ms. Swanson's class: 5 zits/kid * 25 kids = <<5*25=125>>125 zits
Then subtract the number of zits in Ms. Swanson's class from the number in Mr. Jones' class to find the difference: 192 zits - 125 zits = <<192-125=67>>67 zits
