Checkup: Where are You?
=======================

Getting Un-stuck:

* try to solve the problem

  * if you're just heading off to do surveys or play games you likely aren't 
    going to figure out how to code anything
  * ask me, ask your friends, but keep **trying**
  * there's only a few hours left in the club this year
  
* you don't have to wait for coding club to code see :doc:`installation`
* reading is pretty important... if you're **not reading**, 
  you're **not going to understand** the instructions here
  
  * if you are having trouble with reading, we may need to switch you to a 
    graphical coding environment for now, please see me
  * programmers actually spend a *lot* of time reading, it's the only way 
    to figure out how things work much of the time

* there are other ways to learn to code see :doc:`links`
    
Puzzles
--------

Try to answer the following puzzles. **If** you get stuck, try writing/running them,
if you still don't understand, read and/or ask me. If you don't get these 
ideas you're going to get lost!  Getting lost can be fun, but it's more 
fun if you're lost in an interesting area.
