Adequate sources for World History studying

<p>So ,I ve been preparing for my world history subject test in December but I just dont think Princeton review is enough.After completely covered their review pages,I still miss about 25 questions and I need to reduce this to ~15 in order to get 800.Still,I have about three weeks but I also have Math lvl 2 test to study for …
What do you suggest ?Some good online materials …I heard Barrons is very comprehensive but also it covers too much extra material and ,sadly,no time for this.</p>

<p>come on ? no one ?</p>

<p>three weeks is more than enough :wink: try Barrons out.</p>
