THE Dons passed their Skolars test with flying colours to stay in contention for a top four finish in Championship One.
Tony Miller’s side were not at their best before the break but still took an 18-10 lead into half time against a London side who are much tougher proposition this season.
The visitors then closed the gap to two points at the start of the second half when David Williams burst through a static defence.
But as the Skolars ran out of gas, Doncaster got better as the game wore on and tries from Dominic Dee, Nev Morrison, Chris Spurr and Carl Hughes wrapped up a fourth win on the bounce.
Skolars took a surprise lead after five minutes when full back James Anthony skipped through the Dons defence to score.
Their four point advantage lasted just seven minutes as the impressive Morrison finished off a sweeping move and Scott Spaven’s conversion edged the home side in front.
Jack Ely powered over between the posts midway through the first half and Spaven’s kick gave Doncaster an eight point lead.
But London responded when Mourad Kriouache got in between the posts and Dylan Skee converted from point blank range.
The visitors fancied their chances of an upset but Craig Robinson brilliantly bulldozered his way over the line from five yards to help give the Dons an 18-10 lead.
Williams’ try then gave London brief hope but the Dons moved through the gears and got their reward.
Dee went over between the posts, Morrison grounded in the corner, Spurr rounded off a lovely passing move and Hughes was on hand to finish after neat work by man of the match Spaven, who kicked six goals.
