I always try to explain in detail ,any topic either that is easy or Hard . Because I believe neither any topic is hard nor any topic is easy .Its depend on your knowledge and concept about that topic. That's why I always try to make deeper concept in all topic which I study instead of only studding it on surface level.
so, feel free to ask any type of question ,I will try my best to explain to you. SO keep learning and keep growing and always be happy bcz when you study with happy mind you are more focus at that time and during studying you will feel very light instead of burden feeling.
