I have complete my 1month plan with 2024th edition verbal series. I am doing question from big book just got for TC
Test 1 6/14
Test 2 5/14
Test 3 7/14
So should I also see Dedicated series season 1 , 2 , 3.
Or it will explode my brain ??? 
Yeah, its worth doing one of the other seasons.
Season 4 is probably the most recent one that’s complete and has ETS questions: Dedicated TC and SE Season 4 - GregMat
