do you get one for each class or must you complete them all. Also what is the difference in the first lesson and second of begining? i know a little already I need to know how to go into the woods and get my own and where to start from there. how to make a large tree with an already large trunk into a smaller tree, how long after that do you leave it in a regular grow pot until limbs form because they are so far up usually on the already larger taller trees. so when you cut them you are left with a bare trunk sometimes and roots. Also the pruning and potting shaping all of it except the last two 7.99 courses.
