would agree with Jim, start with something simple, a negative that needs just dogding for instances, or perhaps burning; begin with the basic exposure and dodge out the last >>>>>>>fill in times>>>>>>>>. With a burn, exposue for the basic time, then just burn in the necessary area after that.
As you begin to have more complicated prints, it is critical to keep carefully records for each step. Some of my students take the first test print, sit down and with a sharpie, mark off the areas with the adjusted times that may work, then use that as a guide when they begin to work on the print; making changes on a mapping guide that will end up with the changes.
When all the testing has been completed and all changes have been decided they take the test print with the changes and have it next to them while printing , checking off the areas to be sure they have covered the "field".
After all is done, they keep the "mapping record", manner varies with style of the owner.
Start with small steps first, then build on each step. Becomming a good printer let along outstanding one is practice, practice, and more practice.
One additional tip. the better you make the negative the easier the work is in the darkroom. For every hour you spend thinking and making the decision before pushing the shutter will save several hours of work at the printing stage.
Have fun and realize, you will need to fill the "learning bin", regardless; it is just part of the process
