 2. Create prompt injection attacks to manipulate the grading process
-3. Test attacks against different models (GPT and Claude)
+3. Experiment with modifying the system prompt (Part 2)
 4. Document their approach and findings
 
+The lab is divided into two parts:
+- **Part 1**: Basic prompt injection attacks on the default system prompt
+- **Part 2**: Advanced attacks involving modifications to the system prompt
+
+### Student Interface Features
+
+The Gradio interface includes:
+1. Student identification field (university email)
+2. Submission text area for entering code or injection attacks
+3. Additional system prompt field for Part 2 experimentation
+4. PDF report generation for documenting successful attacks
+
 ### Learning Objectives
 
 - Understand how LLMs process instructions in system prompts
 - Identify vulnerabilities in LLM-based systems
 - Execute successful prompt injection attacks
-- Compare model vulnerabilities across different LLM providers
+- Learn about system prompt design and vulnerabilities
 
 ### Evaluation Criteria
 
-Students should submit a report containing:
-- At least three different prompt injection attack examples
-- Documentation of each attack's methodology and results
-- Analysis of which models were most vulnerable and why
-- Suggested mitigations for the vulnerabilities they discovered
+Students should submit:
+1. The PDF report generated by the interface, containing:
+   - Their student ID
+   - A record of all attack attempts
+   - The submission text for each attempt
+   - Any additional system prompt instructions used
+   - A score history chart
+
+2. A written analysis explaining:
+   - At least three different prompt injection techniques they used
+   - The vulnerabilities they identified
+   - How they structured their attacks
+   - Potential mitigation strategies
