Changes in scores

I've been noticing some pretty scary things, so I've started trying to take a test every couple of weeks. Here are my results:

12/11/12 - 123 points, with 7 serious concerns.
01/03/13 - 134 points, with 8 serious concerns.
01/14/13 - 139 points, with 9 serious concerns.
01/28/13 - 130 points, with 7 serious concerns.
02/08/13 - 144 points, with 10 serious concerns.
I'm 15, 5"2 with a BMI of 21.5. No diagnosed mental conditions. Asthmatic. Are dips, then new top scores normal? I also think this is kinda high for me, should I do something about it (if possible)? My entire family have had severe depression at some point, one of my brothers has bipolar and the other has (we believe) undiagnosed Aspergers.
Has anyone else had similar results?

The test is totally self-scored, it is all based on your own answers to the questions about how well/ill you are doing so it's a little like magazine tests? It would vary according to how you are feeling about yourself and problems when you take the test, whether you're anxious about the results, etc. It's mostly just to see if there are any "surprises" you didn't know about and as there are almost 300 questions, anything in the range you are getting is pretty close to "average". Not a whole lot can be figured out taking it so often but maybe next time you take it, decide you want to give the "best" answers you can, the most positive ones, and you'll see you will get a lower score? It's not that one is lying about the answers, just that they are very subjective and based on your mood and current thoughts/issues.

If you see a therapist or psychiatrist, maybe print out one of your results to share with them and discuss. It's a good little gadget to have to discuss with one's doctor and wonder about but not any good for diagnosing or showing you anything specific about possible future problems.
