If you are comfortable solving at least two of Problems #1-3, you should be in our advanced intro CS class at bectutoring.com/intro-cs. This class will assume experience using functions, loops, variables, and conditionals. We will cover javascript syntax. If this doesn't sound familiar, not a problem! Please sign up for our novice CS class at bectutoring.com/intro-cs.
#2
Assume you have a function to draw a circle of radius r. Draw a circle of radius 100. Then use a loop to draw as many concentric circles (circles with the same center) as you can inside of it. Each circle will have a radius that is 10 smaller than the previous one.

#4
Write a function that takes an array (a list) of numbers and returns the second largest value in the array.

Then, write a function that takes a string and returns a new string with all the spaces removed, and all the letters made lowercase.
If you are comfortable solving Problem 4 and have experience with basic string manipulation, arrays, HTML, and CSS, you are most likely too advanced for both of our classes. We are happy to design an individual learning plan. Contact us at info@bectutoring.com.
