yes ofcourse you can do it... but remember one has to repeat the history at least twice... and you should divide it in the following pattern...
1. Independence movement and war
2. constitution making
3. Federalist regime and anti-federalists
4. 1800-1837 presidents and events are important from paper point of view
5. Civil War 0f 1861
6. from 1898 to today...
- progressive movement
- president woodrow wilson
- President FDR
- Truman
- Eisenhower
- watergate scandal
- vietnam war
these are important topics regarding the paper... and yes you must go through the past papers so as to understand which topics are important... you don't need to cram these two books in its entirety because this subject is of only 100 marks....
