Does this mean it will stay in my system longer? On and off I've used adderall xr over the years. Just yesterday and today I've taken about 120mgs over the last 2 days. I'm not doing any more, I'm done. but i start cna classes the beginning of January, they are 3 weeks long and I'm pretty positive they give the drug test after you pass the classes. I'm deathly afraid I'm going to fail because of how much I've abused this drug over the years. Should i be worried?? and if they do give it at the beginning of the classes, what are my chances of passing?

Factors such as age, health, metabolism and dose and frequency of use all affect how quickly a drug is eliminated from your system.
Ass long as you don't take any more you should be fine for your drug test.
Here is the technical stuff...
The half life of Adderall is about 10 hours.
This means that every 10 hours, half of the previous amount of Adderall in the body disappears.
For example, if you took 10mg of Adderall at 12AM (midnight), at 10AM 5mg of Adderall will be left in your body. At 8PM, 2.5mg will be left, and so forth until there is 0mg left in your body.
As a rough guide it takes about 5.5 half lives for a drug to be out of your system. For adderall then it would take just over 2 days for a dose to be out of your system.
(5.5 x 10 = 55 hours - which is just over 2 days)

I too have a problem with this drug. It seems to help me get things done and helps with my concentration, etc. I got surprise drug screen today. A observed drug screen. I did one 20 mg adderal 3 days ago, I hadn't done any adderal in over a week and the capsule was broken and some of the beads were gone. So if it is true what I have read about it having a 10 hour half life, then, naturally it should be gone.
Over the years I have noticed that no matter how many of these I take, they are completely gone after 4 days. But it has to be 4 complete days.
