Since I've been giving numerical marks on your work, I owe you my explanation of what these mean.
On a warmup homework, the max grade is 5. What does a 4 mean? Well, it definitely does *not* mean 80% or a B-.
The 4-5 range is an A range. 3-3.99 is B range. 2-2.99 is C range.
For the hand-in problems, rescale this rule. So 16-20 is an A range, etc.
There will be no grading curve. Curves mean competition, and we aim for collaboration. If everyone ended up with 4.5 / 5 for their average over all homework, the test and project; everyone would get an A.
Nothing would please me more than to have this be the case :-)
