For looks and sturdiness its a 5/5. 

For building it was a 3/5. The instructions have you mix screws from pack A and B in the same build step which are similarly sized and I used an A screw in a B slot and pulled out one of the anchors from the wood panel. I had to get a drill bit to split the anchor in 2. Luckily I was able to put the anchor back in the wood panel after and was able to successfully build with B. 

But yeah I normally make a few mistakes in a build and I give lower marks where a mistake can lead to total build failure, in this case I salvaged it just fine and got a beautiful table.
