Best question type: Proofs and matrix operations.
Sample Q1 (Eigenvalues):
Given matrix ( A = \beginbmatrix 2 & 1 \ 1 & 2 \endbmatrix ): a) Find its eigenvalues and eigenvectors. b) Without computing ( A^100 ), explain how you would find its trace and determinant.
Sample Q2 (Projections):
Derive the formula for projecting a vector ( b ) onto the column space of ( A ) (( A^T A x = A^T b )). Why is this used in linear regression?
You will not write a full deep learning model, but you will implement core data structures and algorithms from scratch. Libraries like NumPy are often restricted to basic array operations; you cannot use high-level ML libraries.

Preparing for the Mohamed bin Zayed University of Artificial Intelligence (MBZUAI) entrance exam is a daunting task, but the release of the official sample questions has been a game-changer for applicants. These samples are not just a study aid; they are a critical strategic tool.
What sets them apart:
For anyone serious about joining MBZUAI, these sample questions are the gold standard for preparation. They remove the guesswork and allow you to focus on what matters: mastering the science of AI. mbzuai entry exam sample questions best
Simply reading the solutions will guarantee failure. Follow this 4-week protocol:
Week 1 – Diagnosis: Attempt all sample questions above with a timer (90 minutes). No notes, no Google. Grade honestly. If you score below 60%, delay your application.
Week 2 – Math Drills: For every linear algebra question, derive the proof twice – once forward, once backward. For probability, simulate the Bayes question in Python to build intuition.
Week 3 – Coding Without Autocomplete: Re-do the Python questions in a plain text editor (not VS Code with IntelliSense). MBZUAI’s proctored environment is often a stripped-down Jupyter notebook with no syntax highlighting.
Week 4 – Mock Exams: Combine 4 math questions + 4 coding questions + 2 conceptual questions. Set a timer. Grade strictly. Repeat until you consistently score >85%.

The MBZUAI online screening exam is a critical 45-to-60-minute assessment consisting of 40 multiple-choice questions. It evaluates foundational skills in Mathematics, Programming, and, for specific tracks, Machine Learning and computer science specializations. Core Exam Topics
Based on the official MBZUAI Admission Guidelines, the test covers these primary areas: Mathematics: Calculus: Derivatives (e.g., ) and optimization.
Linear Algebra: Matrix operations, eigenvalues, determinants, and matrix invertibility.
Probability & Statistics: Sample spaces, mutually exclusive events, and basic probability (e.g., dice rolls or ball draws without replacement). Best question type: Proofs and matrix operations
Trigonometry: Solving equations with sine, cosine, and tangent. Programming (Python):
Core Concepts: For and while loops, recursion, and object-oriented programming (OOP).
Data Structures: Understanding stacks, queues, and singly linked lists.
Algorithms: Time complexity (Big O notation) and basic search/sort algorithms like Bubble Sort. Machine Learning (MSc/PhD applicants):
Regression: Key differences between Linear and Logistic Regression.
Optimization: Concepts of Gradient Descent and loss functions.
Fundamentals: Supervised vs. unsupervised learning, bias-variance tradeoff, and evaluation metrics (F1-score, Precision, Recall). Sample Questions
Official sample materials from MBZUAI guides and student resources include:
Regression: "Which is true? Linear Regression predicts continuous variables; Logistic Regression predicts categorical variables." (Answer: Both are true).
Probability: "From a bag of 6 red and 2 blue balls, what is the probability the second ball drawn is red if drawn without replacement?". Given matrix ( A = \beginbmatrix 2 &
Python: Identifying the output of a provided code snippet featuring map() functions or while loops. Math: Solving systems of equations like Preparation Strategy MBZUAI Online Screening Exam Instructions
Report Title: Analysis and Compilation of Best Sample Questions for the MBZUAI Entry Exam
Date: [Current Date] Prepared For: Prospective MSc/PhD Applicants to MBZUAI Subject: Recommended question formats, difficulty levels, and preparation resources for the MBZUAI admissions test.
Before diving into the questions, you must understand the exam's philosophy. The MBZUAI entry exam is not an IQ test; it is a prerequisite audit. It assumes you have a Bachelor’s degree in Computer Science or Mathematics (or equivalent) and wants to ensure you can survive the first semester.
Key facts:
Warning: The "best" sample questions are useless if you ignore the time constraint. MBZUAI questions require deep reasoning, not speed-solving.
Question 1 (Matrix Properties) Given matrix ( A \in \mathbbR^n \times n ) and a non-zero vector ( x ) such that ( Ax = \lambda x ).
Why this is a "best" question: MBZUAI rarely asks "Find the eigenvalues of [[2,1],[1,2]]". They want proof of the underlying spectral theorem.
Question 2 (Vector Calculus for ML) Let ( f(w) = \frac12 | y - Xw |^2 ), where ( y \in \mathbbR^n ), ( X \in \mathbbR^n \times d ), ( w \in \mathbbR^d ).
Pro tip: In the real exam, you must do this by hand. Memorize the matrix derivative rules: ( \nabla_w (w^T A w) = 2Aw ) (if A symmetric).
