What NOT to Over-Study
Don't Waste Time On
- Deep math - No calculus or linear algebra required
- Coding implementation - Conceptual understanding, not code
- Training algorithms - Focus on use cases, not backpropagation
- Specific pricing - Know models, not exact costs
- Advanced ML theory - This is a practitioner exam, not data scientist
⏱️ Time Management
Exam Format
- 120 minutes for 85 questions
- About 1.4 minutes per question
- Mix of multiple choice and multiple response
Strategy
First Pass (80 minutes):
- Answer questions you know
- Flag uncertain questions
- Don't spend more than 2 minutes per question
Review Pass (35 minutes):
- Revisit flagged questions
- Eliminate wrong answers
- Make educated guesses
Final Check (5 minutes):
- Ensure all answered
- Quick double-check of marked questions
No Negative Marking
Always answer every question. No penalty for wrong answers!
