 The LLM course is divided into three parts:
 
-1. 🧩 **LLM Fundamentals**: this part covers essential knowledge about mathematics, Python, and neural networks.
-2. 🧑‍🔬 **The LLM Scientist**: this part focuses on learning how to build the best possible LLMs using the latest techniques
-3. 👷 **The LLM Engineer**: this part focuses on how to create LLM-based solutions and deploy them.
