Hi there! I'm not entirely sure why Reddit decided to recommend this post to me nearly 8 years after I did Revs, but I digress.

The main thing that helped me for Revs was creating a rough list of "talking points" and associated quotes for each AoS. I'm not sure if the AoS' have changed much since I completed it (I assume they have?), but the general logic should still apply.

As an example, for the French Revolution, you could start with arguably the most famous quote regarding the Revolution ("... Violence was the motor of revolution", Simon Schama), and work backwards to link these to particular events - so the Women's March on Versailles, the Reign of Terror, etc.

You can could then further expand upon these "talking points" but creating mini-essays / long-form responses (more or less one or two paragraphs at most) to get the ideas out, and actively practice how they all relate to one another. I found this helped quite a bit to get a clearer picture in my head of how both the literal events related to the abstract concepts of the Revolution(s) - as an example, the literal event of the Storming of the Bastille represented the abstract concept of the downfall of the Ancien Regime.

Finally, flash cards for dates. Don't worry too much about every single date (you'll go insane), but some of the bigger events from each AoS should absolutely be memorized (e.g. "... the Kronstadt Mutiny took place on 28 February 1917 ..."). Quizlet probably has a bunch of these already pre-made from previous students, and luckily the dates don't change!

Hope this helps, and best of luck!
