I have completed my B-tech,since my childhood days I have been practicing calligraphy and even participated in many competitions.I have an experience of 7 years in calligraphy tutoring
Experience: 7 years
Most skills can be self-taught, as long as there is dedication, a willingness to train regularly and for extended periods of time and a high degree of perfectionist spirit. Especially for some forms of Calligraphy like Copperplate (where there is little room for error), or even Japanese or Chinese calligraphy (sense for aesthetics is highly important.)
I've heard many experienced Calligraphers say they are self-taught, having practised for decades. They all claim the same thing, calligraphy is a skill of practice, and anyone can do beautiful writing with dedication.
For resources, it depends on what kind of Calligraphy you are after. For english pointed pen ones is a good resource. For manuscript styles (with flat tip nibs) like Gothic styles, I find books to be more helpful. For Uncial, foundational, Batarde, etcetc, I borrow them from public libraries, or look at exemplars from other Calligraphers for inspiration (for modern styles)
