Python Institute PCAD exam guide covering pandas, NumPy, data prep, and analysis decisions.
This Certified Associate Python for Data Science guide helps PCAD candidates focus on what the exam tests, where close answers usually split, and which review page to use next.
Use the study plan to prepare Python code-tracing, data-shape, and syntax practice, the cheat sheet for quick recall, the sample questions for applied practice, the FAQ for scope checks, the resources page for Python Institute references, and the glossary when language terms blur together.

| Lane | What to master | Common weak answer |
|---|---|---|
| Python foundations | Use core syntax, functions, data structures, files, and exceptions as the base for data work. | Blaming a library when the issue is basic Python type or scope behavior. |
| Data handling | Understand tabular data, missing values, filtering, grouping, sorting, joins, and reshaping concepts. | Cleaning data without knowing what rows, columns, keys, and missing values mean. |
| Statistics and visualization | Read summary statistics, distributions, correlation, charts, and common interpretation traps. | Confusing correlation with causation or average with distribution. |
| Machine learning basics | Understand train/test split, features, labels, overfitting, metrics, and model evaluation. | Judging models only by training accuracy. |
| Data ethics and workflow | Recognize bias, privacy, reproducibility, documentation, and responsible use. | Publishing results without reproducible steps or data-quality notes. |
Data science Python questions reward data-shape awareness: clean, summarize, visualize, model, evaluate, and explain responsibly.
