im really dissapoitned in my vb expirience i started to learn Vb like 4 years ago but quit for a while i just joined Intro to VB at my school and ive been doing better, but today its been horrible we had a pop quiz and basically we had to make a calculator that could just add and multiply number , its just everytime i cant use references basically ( looking at peoples work) i just cant seem to remember any code or anything , basically the teacher wanted us to try and figure out on our own, i ended up with 567 lines of code till i gave up i typed each of the solutions line by line yeah im stupid,

basically my question is how can i learn Vb From the lowest stuff to the highest stuff ( complicated)
