You can sooo do this! Charts can be intimidating. A couple suggestions:
1) Use a post it note to place directly under the row you are currently working on, thus covering up the parts of the chart you have already done. You'll know exactly where you are.
2) Before diving into it, mark arrows on each line showing the direction you are suppose to go on. Most charts start out right to left, then 2nd line is left to right, 3rd line right to left and so on.
Hope this helps a little, any other suggestions?
