Hi I will be doing a stacked cake for my Wilton Course 3 final cake BUT for the bottom do you use a more sturdy board like plywood or a special board for such a heavier cake. I no for sure a cardboard won't hold a 10", 8" and a 6" stacked cake. Any suggestions?
You could use plywood or masonite, or you could just double or triple up the cake boards under the bottom tier.
Sure it will be heavy. Get a cake drum (picture attached), you can buy it at michaels, they come in packs of 2.
Or if you want a cheaper option go to your hardware store and buy some thick Masonite, I buy them at homedepot for $1 (12x12in) and my husband cuts them for me.
For a not-so-heavy stacked cake you can take 3 cake boards and line them up so the corrugation of the cardboard goes different directions (not all lines going the same way), tape them or glue them together, then cover the whole thing with fancifoil. I wouldn't try this on a 6, 10, 14" or anything if you're wanting to move it as one stacked cake, but for a 6" and a 10" or if you're moving the layers separately, it'd be fine. Just support the bottom well when carrying, because if cardboard flexes, the cake flexes....
I usually like the Michael's cake bases, ready made and strong.
Gosh my instructor made it sound so easy she even told us a way to stack them and secure them so we could travel with the cake already assembled. I will probably take it to class in pieces and then once it's done you can't take it apart, so I was going to drop it off at DH's work 2 miles from Micheal's so no big deal if it sits in the car right as long as put some padding underneath. What is masonite?
I like to use the masonite boards and wooden dowels. It is really sturdy and you can travel with the cakes stacked and decorated. I got mine at Sugarcraft and covered them with contact paper so they are reusable. You can buy a small miter box and small saw at the hardware store to cut the dowels with; on larger cakes I use larger dowels and cut them so the cake board is resting on the dowels and not the cake. Be sure and put a dollop of icing under each cake to prevent sliding 
Don't forget to put something under the base to prevent sliding while traveling- This has worked really well for me!
