You should be gradually working up to speed, especially in unfamiliar conditions, so that you simply don't enter corners at a speed that is grossly beyond what you or your bike can do. Overcooking the entrance or misjudging a line happens many times; part of finding out how much you can do involves finding out what's too much.
Lately, I have seen a lot of offs across different organizations because people haven't followed this approach.
To the OP there is some good advice given in this thread. Also, scout has brought up a good point as well. Get some books, Youtube, Ken Hill, Life at Lean, Motovudu and others all provide great information.
For me the more I ride track days, the more I understand the topics and can apply what I hear and read to the topic.
A good example is what was mentioned above entry to apex, apex to exit. Understanding the difference in corners and the techniques to apply to each corner is huge. When I started I just sent it, so to speak. In time I realized to get better I had to change and learn the techniques.
Showing interest is great, but I think you have to do several track days to start to understand what you don't know.
