Pro Tips for Choosing Your Topic

• Avoid 'The LEGO Story': Admissions officers have read thousands of essays about playing with LEGOs as a child; start with a sophisticated technical problem instead.
• Quantify your impact: If you mention a project, include specific metrics like 'reduced latency by 15%' or 'increased load capacity by 200kg'.
• Connect the 'Why' to the 'How': Don't just say you want to save the planet; explain the specific engineering methodology (e.g., carbon sequestration) you intend to master.
• Use the 'Theory-Application' bridge: Pick a concept from your undergraduate studies and explain how you applied it to a real-world internship or personal project.
• Show, don't just tell, your ethics: Instead of saying you are 'ethical', discuss a time you had to weigh cost-efficiency against safety or environmental impact.
