This is just a lil thing i realized, since the mobs have become a lot cleverer now and can see through glass, it makes the mob trap so much more effective since there is little blocking and skeleton's getting trapped.

If your wondering how to make this xp farm, just go on youtube and type how to build an xp farm, and there are loads, it is a really simple design and not at all hard to build!!

I hope this helped you out if you do have one of these trap's already, why not check out my channel aswell, i've built a contraption that allows me to switch between loot or xp, so if you want a tutorial on that i will be getting it uploaded soon!! My Channel - iMynaar
