Mathematics, made visible.

I had survived high-school math by memorizing worked examples, and Calculus I destroyed that strategy in three weeks. Ash showed me that my issue was not calculus — it was how I read a problem. Every problem set came back within 24 hours with the exact step where my method broke and one priority for the next attempt. Ten weeks later, limits and derivatives stopped being a lottery.

Five courses, labs, and a linear algebra midterm in four weeks. Every week had a clear sequence: one topic, a targeted problem set, a timed section from a past exam, and feedback before I moved forward. The workload was demanding, but manageable because every assignment had a purpose.

After failing Calculus II, I thought I needed to relearn everything. The diagnostic showed that integration by substitution was the real bottleneck. I practised fewer things, but I practised the right things repeatedly. On my second attempt, I passed with room to spare.

We broke mechanics problems into moves I could practise: draw the free-body diagram first, choose the point that kills unknowns, then write equilibrium equations. By the end, I was not searching for a perfect solution — I knew how to build a solid one.

I expected months of remedial worksheets before touching anything useful. Instead, Ash had me solving simplified versions of real course problems from the first session, rebuilding the algebra underneath as we went. Four months later, I was keeping pace with calculus instead of drowning in it.

I wanted an intensive three-week crash course. After the diagnostic, Ash explained that my foundations made that timeline unrealistic and showed me what a passing grade would actually require. I rebuilt the prerequisites first and moved into exam preparation when the progress checks showed I was ready.
