I'm not keeping them secret at all. We've had discussion about this before. It seems that the best strategy is to set the weight of HW as very small (~10%) with exams weighted heavily but make it clear that exam problems are loosely pulled from HW. Even if you're remote-only, you can ensure all exams are required to be proctored at an approved facility.
