This guide is based on real experiences.
What is GESP? Why is it worth taking?
GESP is a programming ability level certification launched by CCF (China Computer Federation), equivalent to a “level test” in the programming field. What makes it good? In short, three points:
1. Strong Authority: Organized by the same entity as the Sino-International Olympiad, the certificate is highly recognized.2. Strong Practicality: Passing higher levels can exempt candidates from the preliminary round of CSP (for example, scoring 80 in level 7 allows direct entry to CSP-J finals).3. Strong Systematic Approach: Levels 1-8 progress in difficulty, seamlessly connecting with competition content.
The exam is held four times a year, with offline computer-based testing, including multiple-choice, true/false, and programming questions.
Detailed Explanation of Each Level and Preparation Guide (with Suggestions for Level Jumping)
Beginner Stage (Levels 1-2): Cultivating Programming Intuition
Level 1: Getting Started
Can write simple functional programs.Needs to master: variables, input/output, if statements, loop statements.
Level 2: Establishing Logic
Can handle multi-layer branches and nested loops.Needs to master: ASCII encoding, mathematical functions, complex logic.Teaching Tip: Children with good logical thinking can start taking the exam from level 2.
Intermediate Stage (Levels 3-4): Introduction to Algorithms
Level 3: Data Manipulation
Master binary and bitwise operations.Understand one-dimensional array applications.
Level 4: Basics of Algorithms
Master two-dimensional arrays and four sorting algorithms.Learn file read/write operations.Teaching Suggestion: Have children create a maze game using two-dimensional arrays for more fun.
Advanced Stage (Levels 5-8): Transition to Competitions
Level 5: Basics of Number Theory
Master the Sieve of Eratosthenes and high-precision calculations.Understand the divide-and-conquer principle.Typical Problem: Use the sieve method to find prime numbers under 1000.
Level 6: Introduction to Data Structures
Understand tree structures and traversal algorithms.Master DFS/BFS and simple dynamic programming.Fun Practice: Use binary trees to create an animal guessing game.
Level 7: Basics of Graph Theory
Master graph traversal algorithms.Understand two-dimensional dynamic programming.Application Scenario: Social network relationship analysis.
Level 8: Comprehensive Algorithms
Master minimum spanning trees and shortest path algorithms.Understand applications of combinatorial mathematics.Direct Benefit: Scoring ≥80 in level 8 can exempt candidates from the CSP-S preliminary round.
Ability Progression Comparison Table
| Level | Core Ability | Knowledge Points |
|---|---|---|
| 1-2 | Basic Programming Ability | Branching, loops, basic logic |
| 3-4 | Data Processing Ability | Arrays, sorting, file operations |
| 5-6 | Algorithm Basics | Number theory, searching, tree structures |
| 7-8 | Algorithm Design Ability | Graph theory, dynamic programming |
How to Prepare Efficiently? (with Level Jumping Tips)
Level Jumping Strategies
1. Teacher Assessment Recommendation: Teachers holding PTA-related certificates can recommend starting levels based on the child’s actual level, so there’s no need to start from level one.2. Exam Level Jumping Mechanism: If a single score is ≥90, the next exam can skip one level.3. Focused Breakthrough: Targeted training on weak areas, avoiding a broad approach.
Preparation Methods
Daily Practice: 15 minutes of targeted practice each day.Error Review: Use a table to record mistakes and review them regularly.Mock Exams: Conduct full mock training before the exam.
Practical Advice for Parents
1. Starting Time: Starting C++ in fifth grade and systematically learning algorithms in sixth grade is appropriate.2. Learning Environment: Installing Dev-C++ is sufficient.3. Maintain Interest: After completing each knowledge point, let the child play a small game.4. Competition Transition: Levels 5-6 correspond to CSP-J level, while levels 7-8 correspond to CSP-S level.
Finally, I want to say something practical:Taking the exam is just a way to verify learning outcomes; what truly matters is the logical thinking and problem-solving abilities that children develop during this process.
When a child first uses their own code to make the screen display “Hello World”, the seed of innovation has already begun to sprout.
Teacher Wu’s Tips: Learning programming is like learning to ride a bicycle; you may fall a few times at first, but once you master it, you can ride freely. Give your child a little more time and patience, and you will discover their potential is beyond imagination!
