Experimental Designs
By the time Doc finished, it was clearer.
Aaron had experienced a lightbulb moment. Once Doc had told Aaron about the large differences in designs it became clear. Aaron was unsure how he did not grasp these concepts earlier. Doc let Aaron know that it would still take some practice in order for the concepts to become fully ingrained in memory.
Doc's time, had run out.
Not wanting a repeat of the re-dreaming experience Doc made sure to end the session in enough time for him to get to his next appointment. Important professor work Doc said.
