Every concept.
Every variation.
One library.
Chemsets is a practice library that organizes problems by concept and variation, with full worked solutions for every. single. problem.
Free for one month. $10/month after.
The full shape of every topic.
Chemsets organizes chemistry into 15 categories, each broken down by topic, and each topic broken down further into specific problem types. That third level is the important one. It's the difference between "practice stoichiometry" and knowing exactly which variation of stoichiometry you're working on — and which ones you still haven't seen.
Every problem comes with a full worked solution. Not just the answer. The complete reasoning, step by step.

Problems across every topic and variation
Full worked solutions — for every single problem, no exceptions
Practice with a map, not a pile.
Most practice feels like pulling problems from a stack. You do them, you check the answer, you move on. But you never really know if you've covered the full picture of a concept, or just one version of it.
Chemsets shows you the shape of every topic. You can see which problem types you've worked through and which ones you haven't touched. When you've finished every subtype under a topic, you're not guessing at your readiness. You know.
And when you get stuck, you're never left with just a number. Every problem has a complete worked solution — the full reasoning, in order, so you can see exactly where your thinking diverged and correct it.

No commitment. A full month to see whether it works for you. If it does, it's $10 after that -- Labsets and Chemsets are included in ONE subscription.
