 - **Rich Diversity**: With 3,548 questions paired with 6,620 images, sourced from 10 different coding competition websites, the dataset offers a diverse range of real-world programming challenges.
 
-- **Detailed Annotations**: The dataset includes detailed annotations for images, categorizing them into types `Data Structure`, `Geometry`, `3D`, `Demonstration`, `Math`, `Table`, `Pseudocode`, and `Others`, which allows for a detailed analysis of model performance across different visual information types.
+- **Detailed Annotations**: The dataset includes detailed annotations for images, categorizing them into types ``Linear Data Structure``, ``Tree``, ``Graph``, ``2D Geometry``, ``3D Geometry``, ``Chessboard``, ``Map``, ``Patterns``, ``Math``, ``Table``, ``Pseudocode``, and ``Others``, which allows for a detailed analysis of model performance across different visual information types.
 
 - **Automatic Testing Framework**: Each problem is accompanied by input-output pairs that serve as automated test cases to rigorously evaluate the correctness of the solutions provided by the models.
 
 ## Data Split
-The whole dataset is used as a test set. A  `mini test set`  split consisting of 300 problems is randomly sampled from the dataset for efficient evaluation.
+The test set is made up of 263 problems for efficient evaluation.
