Copy remaining Pattern setup Choose core patterns and set a sustainable cadence.
Select three priority patterns Pick high-frequency patterns like two pointers, sliding window, or BFS/DFS rather than grinding random problems. ~15 min Create a pattern-tagged error log Track each miss by pattern and failure type: wrong approach, edge case, or time and space complexity. ~20 min Schedule four short practice blocks Short daily sessions build retention far better than occasional multi-hour marathons. ~10 min Set a difficulty ramp Start each pattern with easy problems to learn the template, then climb to medium before mixing in hard. ~10 min
Deliberate practice Solve, review, and re-solve for retention.
Solve two timed problems Cap each near 25 to 35 minutes; if stuck, study the editorial, then close it and re-implement. ~80 min Optimize one solution Take a brute-force answer and reduce its time or space complexity, naming the tradeoff explicitly. ~25 min Re-solve one past miss from memory Recall the pattern and implement it cold to verify the lesson actually stuck. ~20 min
Mock and polish Rehearse real interview pacing and communication.
Run a 60-minute mock Do two problems back-to-back under interview conditions, narrating your thinking the whole time. ~60 min Practice explaining approach first State the approach, complexity, and tradeoffs before writing code, the way a strong interviewer expects. ~20 min Update your pattern sheet Add the latest template, edge case, or insight to a one-page reference you can review fast. ~15 min
Spaced review Lock long-term retention across patterns.
Re-attempt last week's problems Re-solve a sample of problems from 7 days ago to confirm patterns transfer, not just memorize. ~40 min Audit weak patterns Scan the error log for the pattern with the most misses and schedule extra reps for it. ~15 min Write a pattern cheat-summary Capture the trigger, template, and complexity for each pattern so recognition gets instant. ~20 min
Common mistakes Grinding problem count without tracking which patterns you keep missing. Skipping review after an accepted solution, so the insight evaporates. Practicing without time limits, then freezing under interview pressure. Reading the editorial and moving on instead of re-implementing from scratch. Coding immediately without stating the approach and complexity first. Pro tips Re-solve problems 7 days later from memory to confirm retention. Write a one-page pattern checklist with the trigger and template for each. Explain time and space tradeoffs out loud before you write any code. Group problems by pattern, not by topic, so recognition becomes automatic. When stuck past your time cap, study the solution, then re-implement it cold. FAQ How should I start the LeetCode study checklist? Start with the first phase, then run one timed Study Spaces sprint before adding more tasks. The goal is execution, not a perfect plan.
What should I do if I fall behind? Copy the remaining tasks, pick the highest-score or highest-deadline item, and restart with one focused block.
How often should I review progress? Review after each sprint and once at the end of the week so the next session starts with a clear first task.

LeetCode study checklist
Focus target: LeetCode
Block 1 (25 min): closed-book recall or one timed practice set.
Break (5 min): mark confusing items without opening a new task.
Block 2 (25 min): correct misses and write the next first step.
Done: one score/error note plus one queued task for tomorrow.
