I am currently just coding in my spare time to try and improve my VB skills (I am new to the language) and I currently have a quiz which generates two random numbers (these numbers are variables from a database) and VB randomized them, it then adds the two numbers and spits out 4 answers and the user does a multi choice and selects the correct ones. My program will also then repeat this process several times and stores each result (answer) in a database and the score of the particular user logged in.

I want to improve the quiz. My quiz is a maths program for children and I wanted to make more questions such as fractions, percentages etc and do them as separate topics within my program but I need a bit of help finding the best way to do so. This is my code so far. I have put it into an Imglur album: https://imgur.com/a/EMQoX
