Real RC would be like the Topscore. Question and the passage on the same page. and I think in CDR and Topscore, if you move on to a next question, the passage stays where you stayed last, but in the real RC... if you move on to a next question, it always goes back to the beginning of the passage.
RC was the sole reason why I delayed taking the DAT for so long until finally getting over it. I still did bad lol! but I feel okay with my RC score. Good luck to you!
