A few easy AP to get in BTD5 would include:

Reverse Perfection - 200 AP for completing any 19 tracks on reverse difficulty regardless of difficulty. Used to be harder back when this achievement was initially released as there were only 19 tracks available but with the addition of several new ones, you won't even have to accomplish anything harder than an intermediate track on easy difficulty.

Expert Reverser - 50 AP for completing any expert track on hard difficulty on reverse. Although certainly harder than above, it only includes completing a single track. I would advise doing this on a track like Clock or whatever you think is the easiest track to do it on and if you ever need a boost then the use of special agents and other additions won't hurt much.

Extreme Tracks on hard difficulty - 250 AP for Main Street and 500 AP for Bloontonium Lab, not sure if you've already done them but they offer extremely large amounts of AP. Once again, the utilisation of agents, premiums and specialties might be necessary for an almost-guaranteed victory. These tracks have been out for a long time so I'm sure you can find plenty of guides on youtube or on the NK forums to assist you.

There are of course plenty of other AP jackpots amongst the several medals available ingame but they usually require a lot more dedication and can be rather tedious to obtain. Hope this helps :)
