Edit: Finally the last challege complete :D . I did it thanks to dertswa687o 's "Doctor of the Peggle Arts" achievement guide.

The Doctor of the Peggle Arts achievement in Peggle worth 282 pointsClear all pegs and bricks in every level in Quick Play or Adventure mode and gain explodious fame!He/She gives you tips for clearing a level, and almost every tip can be used for last challenge, except those that you need the green peg in a position that you don't have, because the guide says reset until you have something similar.
And watch videos about (random level) 100% . It's your choice if you follow the guide or the videos. (I watched Franz Setina 's solutions)
And last, for "Tula's Ride" level, I found a video that you can clear the level with ONE peg with Claude.
-----------------------------------------------------------------------
First, I found every challenge complete in Youtube. You can't do the same that the video because orange pegs placement are random, but you can learn and see the master for that level.
Second, I was playing challenge 14-1 (750.000 points), and I scored 1.010.590 points, but I didn't clear every orange peg in the last level, and if you DON'T clear every peg in the last level, you LOSE. It was frustating.
Third, If you can't do the "Beyond Reason" solution for 750.000 , try "Das Bucket" with Warren. You need to hit with your first ball the 2 green pegs/bricks (Waiting for Triple Score, and Magic Hat or Spookyball), purple peg/brick and get the bonus for slide (Extreme Slide if I'm not mistaken). After that, you need to clear the level to get 100% the 100.000 bonus. I tried this 15 times (When I had the correct powers) aprox. I got almost 780.000 , was very close, but I just can't do the "Beyond Reason" solution. Play this level only if you trust more in luck than in your abilities.
And last, this game is mostly, luck. I had 358.910 points (Warren) when I finished 2nd level, I though that I can't do it, but played anyways the last level of the challenge, and I scored 828.710
