Structured 20-Week CFA Level I Study Plan for Working Professionals

As an experienced CFA study planner and tutor, your role is to construct a comprehensive 20-week study schedule for the CFA Level I examination.

Context:
The candidate is a working professional with limited, but consistent, study hours each week. The primary goal is to pass the CFA Level I exam by focusing on efficiency, topic weighting, and practical application through practice questions. The study period is exactly 20 weeks leading up to the exam.

Task:
Develop a detailed, week-by-week study plan that integrates all specified requirements. The plan must be actionable and account for the realities of balancing work with intensive exam preparation. The output should be structured to guide the candidate from initial assessment through to the final pre-exam week.

Constraints:
1.  **Duration:** The plan must span exactly 20 weeks.
2.  **Candidate Profile:** Tailored for a working professional. Assume an average of `{{weekly_hours_available}}` hours available for study per week.
3.  **Topic Prioritization:** Emphasize high-weight topics as determined by the CFA Institute. This typically includes Ethics, Financial Statement Analysis (FSA), Fixed Income, Equity Investments, and Quantitative Methods. Allocate study time proportionally, ensuring these areas receive adequate depth.
4.  **Practice Focus:** End-of-Chapter (EOC) questions from official curriculum or reputable third-party providers must be the primary method for reinforcing learning and identifying comprehension gaps.
5.  **Spaced Review:** Implement a recurring spaced review mechanism to prevent knowledge decay and consolidate understanding of previously covered topics.
6.  **Mock Exam Cadence:** Integrate at least two full-length mock exams into the schedule, strategically placed to simulate exam conditions and identify weak areas for final review.
7.  **Pre-Exam Week:** Dedicate the final week exclusively to comprehensive review, light practice, and mental preparation, not new material.
8.  **Red-Flag Checkpoints:** Include specific points in the plan (e.g., end of month 1, end of month 3) where the candidate should perform a self-assessment to identify significant knowledge gaps or falling behind schedule, with suggested corrective actions.
9.  **Date Integration:** Assume the exam date is `{{exam_start_date}}` and structure the 20 weeks backward from this date.

Output Format:
The study plan must be presented clearly with the following sections:

**I. Initial Diagnostic & Setup**
    *   Brief instructions on how to begin.
    *   Guidance on initial self-assessment.

**II. Weekly Study Blocks (Week 1 - Week 19)**
    *   For each week, detail:
        *   Primary topics to cover.
        *   Estimated hours per topic (proportional to `{{weekly_hours_available}}`).
        *   Specific EOC question targets.
        *   Integrated spaced review topics from previous weeks.
        *   Any red-flag checkpoints.

**III. Spaced Review Strategy**
    *   A consolidated explanation of how spaced review is integrated throughout the 20 weeks.

**IV. Mock Exam Cadence**
    *   Specific dates or weeks for each mock exam.
    *   Recommendations for post-mock analysis.

**V. Pre-Exam Week (Week 20)**
    *   Daily breakdown of activities: final review, light practice, rest, logistics.

**VI. Red-Flag Checkpoints & Contingency**
    *   A summary of all checkpoint weeks and suggested actions if the candidate is off track.
