BMI, calorie needs, macros, meal plans, training volume, 1RM and heart-rate zones: build the numbers behind fitness in a live spreadsheet that checks every cell.
Health & Fitness
Health information is full of numbers: calories and macros, heart-rate zones, risk ratios, survival curves, doses. These courses teach you to compute them yourself in a spreadsheet, with every step checked, so you can read studies, data from your own devices and public-health figures with a sharper eye.
The 20 courses range from nutrition and running maths to wearable data, blood-pressure and glucose analysis, dosage calculations, pharmacokinetics, epidemiology, epidemic models, clinical-trial and screening statistics, health economics, psychometrics, workplace safety and EMS response analytics. All content is educational and does not replace advice from a qualified professional.

Health & FitnessFirst-order elimination, half-life and k from two levels, volume of distribution, clearance and AUC with the trapezoid rule, accumulation to steady state, time to plateau, infusions and the effect of kidney function, all in a live spreadsheet that checks every cell. Placeholder drugs and illustrative parameters only, not clinical guidance.
Health & FitnessScore a questionnaire like a psychometrician: reverse-keyed items, missing-item rules, z- and T-scores, Cronbach's alpha by hand, corrected item-total correlations, alpha if item deleted, test-retest reliability, SEM and reliable change, norm tables and percentile ranks – 8 labs on one fictional wellbeing scale with synthetic data, every cell checked instantly. Not a clinical or diagnostic tool.
Health & FitnessMeasure safety performance like an HSE analyst: hours worked and the incident log, TRIR on the 200,000-hour base, LTIFR per million hours, DART and severity rates, the cost of incidents, leading vs lagging indicators with CORREL, site benchmarks with conditional formatting and a 12-month rolling trend chart – 8 labs on one fictional company, every cell checked instantly. Educational only, no affiliation with OSHA, ILO or any regulator.
Health & FitnessPlan a vaccination campaign by the numbers: target population and coverage goals, doses with schedules and drop-out, wastage rate and wastage factor with multi-dose vials, cold-chain litres vs fridge capacity, clinic throughput, appointment no-show buffers, weeks of stock and reorder points, and a coverage tracking chart – 8 labs on one fictional district with a generic Vaccine X, every cell checked instantly. Logistics practice only, not medical guidance.

Health & FitnessCheck data sufficiency, convert mg/dL and mmol/L, compute time in range, below and above with COUNTIFS, the glucose management indicator, the coefficient of variation, the daily pattern by hour, low events of 15 minutes or more and a weekly summary with highlights and a stacked chart: 8 graded labs on one fictional CGM user's synthetic data. Educational only, not medical advice.
Health & FitnessAnalyse a (fictional) cancer screening programme the way a public-health analyst does: build the 2×2 table from programme data, see how PPV moves with prevalence, pick a cut-off with Youden's J and colonoscopy capacity, combine two tests, measure yield, NNS, uptake gaps and cost per QALY, and put numbers on lead-time and length-time bias, every cell checked live.

No. The courses teach calculations with illustrative data. Diagnosis and treatment belong with doctors, pharmacists and other qualified professionals.
They are practice for the calculation methods used in nursing and pharmacy training. Always follow your programme's and employer's protocols.
Each course is a single purchase of $9.99. That covers every lesson and lab, the final exam and the certificate, with no subscription and nothing that renews.
