Every exam section mapped to a conversation with Ari.
Understanding Python's module system, import mechanics, namespaces, and the standard library modules tested on PCAP including math, random, and platform.
Creating, structuring, and distributing Python packages. Understanding __init__.py, package hierarchies, and pip.
Understanding Python's exception mechanism, try/except/else/finally blocks, and the exception hierarchy.
Creating custom exception classes, raising exceptions programmatically, and exception chaining.
Python string methods, operations, formatting, and comparison. Covers the essential string manipulation tested on PCAP.
Advanced string topics including encoding, bytearray operations, and file I/O with strings and bytes.
Core OOP concepts including class definition, instance creation, attributes, methods, and encapsulation in Python.
Single and multiple inheritance, method resolution order, the diamond problem, and polymorphism in Python.
Advanced OOP patterns including dunder methods, class/static methods, composition, and introspection.
Covers generators, iterators, closures, lambda functions, list comprehensions, and other functional programming concepts tested on PCAP.
Not flashcards. Not video lectures. A conversation that adapts to what you actually need.
Ari starts by finding out what you already know. Already solid on string methods? Skip it. Struggle with multiple inheritance? Deep dive.
"A company needs to extract data from scanned invoices. Which service?" — Ari generates unlimited scenario questions tailored to your gaps.
Track mastery per topic. When all 12 hit "confident" — you're ready to book the exam with confidence.
Not sure if you're ready? Ask about prerequisites, study time, or anything about PCAP-31-03.
