Which session of **Dedicated Reading** to work upon?

I just got the gregmat subscription today. I am pretty weak in RC. I have scheduled my test in the next 2 weeks. So I want to know in Dedicated Reading which session will be enough? Also, do I need to cover all their sessions to get good hands-on RC?
Also plz, let me know the best way to practice verbal and quants on this platform?

Don’t matter , all sessions cover the same material but new insights and better presentation can be seen in newer sessions .

Depends on your ability to absorb the techniques.

For verbal: official material only but for quants you can do whatever you like given you are dedicating enough time for official questions . Here is a list of recommended resources https://new.gregmat.com/recommended-resources
