Regarding GRE Quant and Verbal Timed and Untimed Practice

Hello, after completing the GRE overwhelm plan and strategy series on quant and getting 80 to 85 per cent in foundation overall, I am doing an untimed mock test on quant medium on the website. The test got 65-70%, mostly equal to the class average. So, I am planning to complete all mocks, including hard ones, then, for timed practice, plan to use GRE mini exams on the website.

Do I skip the verbal part in the mini GRE exam because Greg always recommends the big book for verbal rather than websites?

For verbal, I plan to use half of the big book test for an untimed and half-timed format.

Please give advice on my approach.
