Network engineer, 10 years experience, Master's Degree in Internetworking, teaching basic computing and networking.

Deadly! Andrew explained my computer networks assignments very detailed and patient by using various examples. He even wrote a detailed step by step process of how to analyse and calculate networks related quizzes to me. Although I asked him for helping me online, he explained to me very clear, just like a real on-campus class. I can ask him questions at any time. Every lesson, he wrote a detailed google doc material for me, I can still read and review what I learned after the lesson. I felt very helpful!!
