Hello Professor, I wanted to take a moment to sincerely thank you for your guidance and support and investing your time in us. You are the most genuine professors i have ever met in my life who truly wants their students to succeed and that truly is a blessing in itself. I’m endlessly grateful for everything you’ve taught me and I promise you i will not let you down . Thank you once again
Hey Dr. Romano, thanks again for your amazing class. You truly know how to give over the information in a very easy and understandable way, unlike these idiotic professors of ours. I hope like the small token of appreciation from us “orthodox” kids. And enjoy the cotton candy. Looking forward to keeping in touch
