If a single step in your proof cannot be justified by a definition, axiom, or prior theorem, your proof has a "bug." Trace your logic line-by-line just like you trace code variable states. Do Problems Backward: If you cannot prove that , start at
By shifting your mindset from passive memorization to structural problem-solving, treating proofs like code engineering, and systematically analyzing your mistakes, you can fix your trajectory in 6120A and build a bulletproof theoretical foundation for the rest of your computer science career. If a single step in your proof cannot
Whether you're taking 6.120A or preparing for its prerequisite ASE, here is a direct guide to conquering the material: or prior theorem
