Each paper has its own fixed question set. Choose one here to open the timed test, or follow the 45-day study plan for a revision schedule.
Loops, lists, strings and functions — the rules you use every day. Start here.
Start free Paper 1 →Dictionary lookups, exceptions and slicing under time pressure.
Open Pro Paper 2 →Off-by-one, mutation and the cases that look right but are not.
Open Pro Paper 3 →A mixed paper across core Python topics — practise a complete timed sitting.
Open Pro Paper 4 →Trace ranges, branches, loop exits and Python operator rules without running the code.
Open Pro Paper 5 →Reason about aliases, shallow copies, slicing, dictionary order and collection operations.
Open Pro Paper 6 →Trace argument binding, defaults, closures, recursion and local versus global names.
Open Pro Paper 7 →Identify exception classes and trace try, except, else, finally and validation paths.
Open Pro Paper 8 →Practise string transformations, parsing and cursor movement using in-memory text streams.
Open Pro Paper 9 →Understand instance and class attributes, inheritance, bound methods and Python object protocols.
Open Pro Paper 10 →Trace lazy evaluation, iterator consumption, stable sorting and comprehension scope.
Open Pro Paper 11 →Combine earlier concepts in realistic short programs, then diagnose their failure modes.
Open Pro Paper 12 →Your score and review are separate from a percentile. A percentile is shown only after at least 5 learners have an in-time submitted result on the same paper edition. Each learner contributes their best score; older editions are not mixed in.
An open sitting keeps its original questions and deadline. Reopen it with the same account to resume. Answers are saved in the browser while you work. A late submission can be reviewed, but does not count towards percentiles or certificate requirements.
No. An in-time score of 70%+ on any paper meets only the Gold tier’s mock-test check. You must meet its other practice requirements and have Pro to claim Gold. See every certificate requirement →
No. These are PyDebug’s own Python objective practice papers, not official CBSE board papers, a proctored exam, or a separate purchasable Exam Pack.
Certificates are earned from recorded practice, not just from buying a plan. Bronze is free; higher tiers add more requirements.
