Pro Tips for Choosing Your Topic

• Use the 'MEAL' plan (Main Idea, Evidence, Analysis, Link) to ensure every technical paragraph stays focused on a single sub-argument.
• Incorporate code snippets or pseudo-code as 'Evidence' only if they directly illustrate the logic of your paragraph's main claim.
• Avoid passive voice when describing algorithmic actions; instead of 'the data is sorted,' use 'the algorithm sorts the data' to maintain clarity.
• Define technical acronyms (like API, REST, or SQL) upon first use, even if you assume the reader is familiar with them.
• Use transition words like 'consequently,' 'alternatively,' and 'furthermore' to guide the reader through complex mathematical proofs.
