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.

The NLP exam focuses on classic sequence models and basic linguistics.
Sample Question 9 (Perplexity): In language modeling, a lower perplexity indicates: a) The model is more "surprised" by the test data. b) The model assigns a higher probability to the test data. c) The model has overfit to the training data. d) The vocabulary size is smaller. mbzuai entry exam sample questions best
Answer: (b). Perplexity = ( 2^-\frac1N \sum \log_2 p(w_i) ). Lower perplexity = higher probability. MBZUAI uses this to test if you confused perplexity with entropy.
Sample Question 10 (RNN Vanishing Gradient): Why do vanilla RNNs struggle to learn long-range dependencies (e.g., the subject-verb agreement across 20+ words)? a) The softmax activation saturates. b) Repeated multiplication by the same weight matrix leads to gradients approaching zero. c) The loss function is non-convex. d) Dropout destroys the recurrent connections.
Answer: (b). You must mention the chain rule and repeated multiplication of Jacobians. The best sample answer would also note that LSTMs use gating to mitigate this.
The optimal sample questions for the MBZUAI entry exam are not official but are best approximated by graduate-level linear algebra derivations, gradient-based optimization problems, and Python output prediction tasks. Focus on explaining reasoning rather than multiple-choice recall.

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.
