+
+### Example Outputs
+
+#### Example 1: Scholarship Query
+
+**Input:**
+```
+Can I get a scholarship at Sharda University with a GPA of 3.5?
+```
+
+**Output:**
+```
+Yes, you are eligible for a 50% scholarship on tuition fees at Sharda University! 
+With a GPA of 3.5 out of 5.0 (equivalent to 70% or CGPA 7.0/10 in India), you 
+qualify for the 50% scholarship tier. This scholarship is available for eligible 
+engineering programs like B.Tech (which is equivalent to B.Sc. Engineering in 
+Bangladesh). To maintain the scholarship from the second year onwards, you must:
+1) Pass all exams without any backlogs
+2) Maintain at least 75% attendance
+The scholarship covers 50% of your tuition fees throughout your program duration.
+```
+
+#### Example 2: Lateral Entry
+
+**Input:**
+```
+Am I eligible for lateral entry with a Polytechnic diploma?
+```
+
+**Output:**
+```
+Yes, you are eligible for lateral entry into the second year of B.Tech/B.E. 
+programs in India with your Polytechnic Diploma from Bangladesh. Your 4-year 
+diploma after SSC is recognized for direct admission to the second year. Make 
+sure the Indian university's B.Tech program is AICTE-approved to ensure your 
+degree is recognized in Bangladesh. You'll need to provide your diploma 
+certificate, transcripts, and equivalence certificate from the Bangladesh 
+Technical Education Board (BTEB) for the admission process.
+```
+
+#### Example 3: Document Requirements
+
+**Input:**
+```
+What documents do I need to apply to Indian universities from Bangladesh?
+```
+
+**Output:**
+```
+For applying to Indian universities from Bangladesh, you'll need:
+
+1. Academic Documents:
+   - HSC Certificate and Mark Sheet
+   - SSC Certificate and Mark Sheet
+   - Academic transcripts for all years
+
+2. Identification:
+   - Valid passport
+   - Recent passport-size photographs
+
+3. Equivalence Certificate:
+   - From Bangladesh Ministry of Education or UGC
+   - Shows your qualifications are equivalent to Indian standards
+
+4. Additional Documents:
+   - Transfer Certificate (TC) from your last institution
+   - Character Certificate
+   - Medical fitness certificate
+   - Gap certificate (if applicable)
+
+All documents should be attested by the Bangladesh Ministry of Foreign Affairs 
+and the Indian High Commission in Dhaka for visa purposes.

+
+## 🔧 Technical Specifications
+
+### Memory Requirements
+
+| Precision | Memory Usage | Inference Speed |
+|-----------|--------------|-----------------|
+| 16-bit (BF16) | ~8 GB VRAM | Baseline |
+| 8-bit | ~4 GB VRAM | 1.2x faster |

+
+**Recommended:** Use 4-bit quantization for deployment (load_in_4bit=True)
+
+### Generation Parameters
+
+For optimal results, use these parameters:
+
+```python
+generation_config = {
+    "max_new_tokens": 200-256,     # Adjust based on expected answer length
+    "temperature": 0.7,             # 0.3 for factual, 0.7 for conversational
+    "top_p": 0.9,                   # Nucleus sampling
+    "top_k": 50,                    # Top-k sampling
+    "repetition_penalty": 1.2,      # Prevent repetition
+    "no_repeat_ngram_size": 3,      # Block repeated 3-grams
+    "do_sample": True,              # Enable sampling
+    "early_stopping": True,         # Stop at EOS token
+}
+```
+
+---
+
+## ⚠️ Limitations
+
+### Known Limitations
+
+1. **Temporal Knowledge Cutoff** - Information is based on data collected at a specific point in time (October 2025) and may become outdated as university policies change.
+
+2. **Scope Limitation** - The model is specialized for Bangladeshi students applying to Indian universities. It may not generalize well to:
+   - Other countries' education systems
+   - General-purpose conversational tasks
+   - Non-educational domains
+
+3. **Factual Accuracy** - While the model achieves 87.5% factual accuracy, always verify critical information (fees, deadlines, requirements) with official university sources.
+
+4. **University Coverage** - The dataset focuses on major Indian universities accepting Bangladeshi students. Smaller or newer institutions may have limited coverage.
+
+5. **Language** - The model operates in English only. It does not support Bengali/Bangla language queries.
+
+6. **Hallucination Risk** - Like all LLMs, the model may occasionally generate plausible-sounding but incorrect information. Use with appropriate supervision.
+
+### Ethical Considerations
+
+- **Advisory Role Only** - This model should supplement, not replace, professional educational counseling.
+- **Verification Required** - Students should verify all information with official university websites before making decisions.
+- **Cultural Sensitivity** - The model is designed with cultural awareness but may not capture all nuances of individual circumstances.
+- **Bias Awareness** - The model reflects the biases present in the training data and base model.
