assess this letter, please!!

Dear John,

How nice I hear from you and thanks for your reply.
Sorry for my sticking about my request. My BS is in
communication engineering. So I have taken Field and
Wave Electromagnetics, and Microwave Engineering and
the mathematics necessary for it.
My MS thesis was Realism and Quantum Mechanics and I
had to self-study introductory quantum mechanics. I
have read books such as Davies's Quantum Mechanics,
Gasiorowicz's Quantum Physics, and Some chapters of
Sakurai's Modern Quantum Mechanics, though the last
was difficult for me to understand, and I must confess
that my skill in problem solving is not so good as a
physics student; to tell the truth, I think, I am
ashamed to tell it, is not good at all.
I hope this sketch of my scientific knowledge is not
too discouraging and there is a way for a person, by
such a little background knowledge, to continue his
intersted studies by self study. At last I hope the
best for you, and thank you again and sorry
for taking your time.
