Are the Adv classes which started from June 8th same as the Adv class Pre Readings avilable below every live lectures from March 22 - June 6?

Hi,
Yes, the Advanced classes that started on June 8 cover the same Advanced-level concepts as the Pre-Readings available under the live lectures from March 22 to June 6. However, the June 8 classes are structured as the main Advanced classes, so you can follow them directly rather than treating the Pre-Readings as a replacement.
