Chemistry seems like a boring, difficult, and arduous science, like other natural sciences. However, what if I told you that each of us has actually been a scientist since we were little? You must have wondered why the sun exists, why the water is liquid, the grass is green and the sky is blue? So did I, but never got the right answer explained in a suitable and interesting way. Therefore, I asked myself why couldn't I become an educator and try to improve and modify the long-existing school method. Just as my teen years began I took interest in guitar playing and was always fascinated by the tones. The vibrating of the strings made me wonder, what causes the sound? I then researched and explored that certain vibrations caused by the movement of atoms are responsible. Well, then I got only deeper and deeper into it, and eventually fell in love with chemistry. In my early university days, I started teaching at some private primary schools, and my method turned out pretty well. I then upgraded and moved on to give private lessons to my colleagues. A teaching assistant noticed me and offered me a job as a freelancer, or in other words an online tutor. And so did my freelance career started. I then applied for several companies and got my first job. Since then I have been helping students all around the globe! So are you afraid of chemistry? Well, let's fight that fear and finally understand chemistry as a part of our everyday life, not just as a science. Everyone is welcome!
