A basic method for negative evaluation was described years ago by many - called the "proper proof" by Fred Picker (his Zone VI Workship is a good book also, if you can find it, very conversationaly written).
Set up for contact printing - glass under the enlarger if you have it. Expose a test strip, choosing the exposure that is just enough to make a maximum black in the film rebate area (clear places around the image). Adjust contrast till the highlights look good, maintaining the black rebate. You'll get a sense of uniformity of exposure, and other things that are good to know. If you wind up using an extreme contrast grade on either end, you might need to adjust development time. Quality of shadow detail will indicate exposure. Enlarging will give you more sense of where you are, using the contact as a guide.
There is much more to say about all of this, but this is one way to start.
