Sample Saxony Abitur Informatics Practice Questions

Try these sample questions to review concepts for the Saxony Abitur Informatics exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In computer science, an algorithm is best defined as:
A.A finite, precise sequence of unambiguous steps that solves a class of problems
B.Any set of English sentences describing a computer
C.A physical CPU instruction only
D.A database table schema
Explanation: An algorithm is a finite, unambiguous, effective procedure that transforms inputs into outputs for a defined problem class — the foundation of algorithmic problem solving in the Saxon Informatik Lehrplan.
2Which sorting algorithm repeatedly compares adjacent elements and swaps them if they are out of order?
A.Hashing
B.Bubblesort
C.Binary search
D.Depth-first search
Explanation: Bubblesort repeatedly passes through a list, swapping adjacent out-of-order pairs so that extreme values 'bubble' toward one end until the list is sorted.
3What is the typical worst-case time complexity of Bubblesort on n elements?
A.O(1)
B.O(n!)
C.O(n²)
D.O(log n)
Explanation: In the worst case Bubblesort performs nested comparisons across the list, giving quadratic O(n²) growth in n.
4Binary search on a sequence requires which precondition?
A.The sequence must contain only unique values and be unsorted
B.The sequence length must be a power of two
C.No precondition is required
D.The sequence must already be sorted in a consistent order
Explanation: Binary search repeatedly discards half the search interval by comparing with the middle element, which is correct only when the sequence is sorted.
5What is the time complexity of binary search on a sorted list of n elements?
A.O(log n)
B.O(n²)
C.O(n!)
D.O(2^n)
Explanation: Each step halves the remaining interval, so the number of comparisons grows logarithmically with n: O(log n).
6Which abstract data type follows the LIFO (Last-In, First-Out) principle?
A.Unordered bag only
B.Stack (Stapel)
C.Queue (Schlange)
D.Set with no order
Explanation: A stack removes the most recently pushed element first (LIFO), matching the Saxon Lehrplan emphasis on LIFO/FIFO principles.
7Which abstract data type follows the FIFO (First-In, First-Out) principle?
A.Binary search tree root only
B.Hash table collision chain only
C.Queue (Schlange)
D.Stack (Stapel)
Explanation: A queue enqueues at the rear and dequeues from the front, so the earliest inserted element leaves first (FIFO).
8In a singly linked list, each node typically stores:
A.Only an index into a fixed array with no references
B.Only a previous-node reference with no data
C.A complete copy of every other list node
D.A data value and a reference to the next node
Explanation: A singly linked list node holds its payload plus a pointer/reference to the successor, enabling dynamic insertion without shifting an array.
9Which traversal of a binary tree visits left subtree, then root, then right subtree?
A.In-order (Inorder)
B.Pre-order only
C.Level-order only
D.Post-order only
Explanation: In-order traversal processes left, then root, then right. For a binary search tree this yields keys in sorted order.
10Which traversal visits the root before its left and right subtrees?
A.Reverse in-order only
B.Pre-order (Preorder)
C.In-order only
D.Post-order only
Explanation: Pre-order visits the root first, then recursively the left and right subtrees — useful for copying a tree's structure.

About the Saxony Abitur Informatics Exam

Sachsen Abitur Informatik is the written Leistungskurs Computer Science examination for the Allgemeine Hochschulreife in the Freistaat Sachsen, administered under VwV Abiturprüfung 2026 and the SMK Handreichung for LK Informatik. Content follows the sächsische Lehrpläne Informatik: Technische Informatik (von-Neumann architecture, number systems), Datenstrukturen und Algorithmen (lists, trees, sorting/searching, complexity), Programmierparadigmen and Softwareentwicklung (Python/Java), Sprachen und Automaten, Rechnernetze, Informationssicherheit (including RSA and One-Time-Pad emphases), Datenmanagement (relational SQL with joins and aggregates), and Künstliche Intelligenz foundations. This free bank of 100 original English multiple-choice questions trains that conceptual knowledge. It is not a simulation of the official exam, which is written in German across Prüfungsteile A/B/C with practical computer work scored in Bewertungseinheiten.

Exam sponsor: Sächsisches Staatsministerium für Kultus (SMK), supported by the Landesamt für Schule und Bildung. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Saxony Abitur Informatics: Suggested Study Strategy

1Trace list and tree algorithms by hand (insert, delete, traversals) — Lernbereich Datenstrukturen und Algorithmen emphasises Baum and Liste.
2Rehearse SQL SELECT with INNER JOIN, GROUP BY and aggregate functions (MIN, MAX, AVG, COUNT, SUM) until you can write them without looking them up.
3Review von-Neumann components and binary↔decimal↔hex conversions for Technische Informatik tasks in Teil A.
4Contrast symmetric vs asymmetric cryptography and be able to state the One-Time-Pad perfect-secrecy condition and the RSA modular-arithmetic idea.
5Practise reading short Python/Java snippets for classes, methods, parameters and control structures without an IDE — paper tracing is common before the practical parts.
6Know the Teil A/B/C timing rule: submit A within 100 minutes to unlock MMS, Formelsammlung and language documentation for B and C.

Frequently Asked Questions
