You teach me in 6 hours more than what my teacher teaches me in 8 months.

Its almost 4th quarter and I have been struggling all year, my teachers move so fast and there is no time to even process what they are saying, and they skip over so much saying how we should just 'know' as if we aren't taking the class to learn it :, )
Thank you for making these videos you saved my grade

Around the 14:53 mark you typed "System.out.println("fullName substring 1, 6: " + fullName.substring(0, 6));" instead of "System.out.println("fullName substring 1, 6: " + fullName.substring(1, 6));"

You used /t, but why is there only a single space between alpha and beta, but tab between beta and gamma?
