Hi,
my name is Konstantinos Leledakis and I am a Greek teacher (physicist).
I have teached for many years and some of them physics, other math other programming.
(of college or university level)
You can find more about me in my portfolio in MyCV.
I will offer you free notes on your needs for free including in the lessons (if you need lessons)
or I will include analytical notes on how-to for my answers (if not need lessons).
