We want to warn everybody that we will be taking down our curriculum math problems in the next 24 hours. Algebra/Trig and Calculus will be going through a revamp in the next week or two. We are preemptively sorry for any of you who may be working on those problems at the moment they go away.
The types of problems that appear in curriculum math will be incorporated into an expanded version of the Techniques Trainer, which will give you more control over the difficulty and types of problems you see.
Although curriculum math problems are going away for now, they will be reborn in an improved form in a few weeks. Stay tuned.
All the best,
Peter and the rest of the team at Brilliant.
