GMAT June'22 Plan : Magoosh

Greetings,
I recently joined Magoosh and was going through a few resources available. I went through the GMAT 3month plan (https://gmat.magoosh.com/3-month-gmat-study-schedule-pdf-beginners?utm_source=gmatblog&utm_medium=blog&utm_campaign=gmatstudyschedule&utm_term=button&utm_content=3-month-gmat-study-schedule-for-beginners&_ga=2.87239384.1327116869.1645754378-45024995.1645754378)

Resources I'm having-
-GMAT 2022 official guide + Verbal and Apti official guide 2022
- Magoosh self-study classes

While I was going through the 3-month study plan I was not able to understand when and what I will be doing and it's stated to solve 16 questions from apti and 12 from RC which book? And without going through the lectures don't you think it would be like wasting the questions.

Please help me with the plan, I'm serious about it and would love the Magoosh team to help with it.

Regards
Divyank
