Politics I don't think it is necessary to read graphic shorthand or knowledge list. Politics needs to organize notes regularly and memorize them. And accumulate experience in doing problems.
Not to mention geography. In view of the fragmentation of geography, systematic notes are more important. Physical geography, like science, human geography summarizes routines.
To sum up, I recommend the list of historical knowledge. Personally, I don't like graphic shorthand, which is a bit flashy.
I hope it helps you.
