As frustrating as the drone challenges were, they were that much more satisfying to achieve gold on them. I sort of took what i learned playing street fighter iv's combo trial challenge. You disect the whole track in sections, like how it's hard to remember 5554740907, but if you go, (555) 474 - (then) 0907, it's so much easier. Master/memorize the blue orbs in sections. Plus the more you fail, the more you memorize the track in repetition. Same can be said for the stealth ones too. Figure out the route, then just connect the dots with web-strikes (triangle button). The more you fail, the more you start to memorize. Progression.
As for the other 2, bringing spider-bro to combat made things super easy, mix in with spider-drones, it's a cakewalk each time. If that still doesn't work, equip him with all the perks that favor spider-bro, gadget refills, and even maybe focus meter for finishers.
The bomb ones, you just have to use perch into perfect launch as much as youre able to. Holding L2 is your friend, and aiming to perch right on to the bombs themselves also saves valuable time.
