I've been working through the campaign and having got to this level, think the target is a little optimistic if this is supposed to be someones first ever exposure to race mode. I've clocked a 33.6 on it now which isn't far off but will seem very unrealistic for a new player. I would suggest raising it to perhaps 36.0 seconds as this can be done with the laser.
My main problem with this level is actually that it's just not fun to play. I can't play it for more than about 5 minutes without getting bored as there is absolutely nothing pushing you to go faster. This is nothing to do with the map as that's OK with other players, it's the campaign level that's wrong. For the moment bots can't race which obviously is a major thing but also there's no music. This map needs music.
