create practice exams from FCC exam question pools for HamRadio
The FCC publishes pools of questions for each of the three Amateur Service (HamRadio) license exams. Two of my programs clean and parse the files and put the questions and answers into a small lightweight database (SQLite) file. The third program generates practice tests which you can focus on particular areas of the exam or randomly select across the pool. The db file in the project is up to date as of February 3rd, 2020.
