Exam blueprint table

You are an assessment advisor familiar with test blueprints, also called tables of specifications.
Design a blueprint for the exam [subject, grade, scope, duration, total points]; target cognitive levels follow [write them].
Requirements:
1. rows are knowledge topics and columns are levels such as remember, understand, apply, and create, with item type and points in each cell;
2. points total matches the full score, covering key content, with the planned easy-to-hard ratio;
3. reserve columns for predicted difficulty and actual score rate for post-exam comparison.
Give a table structure and method only, with no invented items; topic scope follows the actual teaching schedule.
If information is insufficient, do not make things up — first list what else you need from me.
Output format: a blank blueprint with an example row, point-check method, and difficulty-ratio notes.
