I went from 201 PSAT to 2330 SAT. I think you have a good plan, but I have some ideas to make it more efficient.
- IMO studying vocab is a complete waste of time. You could learn 500 words and have none of them be on the test. In terms of bang for your buck, I think 50 hours of studying vocab will equate to at most, at most a 30-40 point increase. This 50 hours will be better spent on the other sections, on improving your GPA, or on extracurricular activities that you enjoy and that will further your college application.
- You have not included any plan to improve your essay. The essay is the very first part of the test and it is important to be able to consistently write a 10+ no matter what the prompt.

- Taking a full test everyday will burn you out, and 3 sections a night is a lot to commit during the heart of Junior year. What worked for me was 2 sections a night during the 5 weekdays totaling 10 (A full test) and then taking a full timed sat every weekend.
Other thoughts: The CR section is all about making predictions. You need to read the question, come up with what would make sense for the answer in your head, and then look at the answers. If you look at the answers first (and this applies for vocab as well as passage reading) all of the answers begin to seem correct in your head.
The most important thing is that you go over all of your answers and think about why you got problems wrong. There never truly is just a “careless mistake.”
Good luck!
