<li><p>To be honest, Collegeboard’s Official SAT study guide isn’t all that helpful either. I only bought it for the 10 tests that come with it so I could practice the real test in the actual format, but the first 365 pages are all basic facts and strategies like “If you can go down to 2 choices on the multiple choice problems, take an educated guess” or “ratios can be expressed as fractions, with a colon, or using the word ‘to’”; basically things that everyone would know without needing a book. So, I would suggest buying the official collegeboard SAT guide just for the practice tests, but don’t waste your time reading every sentence of the first portion, because it is meaningless.
The first SAT book I bought when I was a complete newbie was “SAT 2400 in Just 7 Steps” by Shaan Patel. I recommend this book so much because it had all the strategies I need for the SAT and helped me so much more than the official collegeboard SAT book’s first 365 pages. My score got 470 points higher on my first SAT than when I took the PSAT (which I didn’t study for at all) after I worked on this book only. Then, I used the methods I learned from “SAT 2400 in Just 7 Steps” and did practice tests every week from the official collegeboard book and got a 2190 on my second SAT. </p></li>
<li><p>As I took practice tests every week and studied the list of vocabulary words in “SAT 2400 in Just 7 Steps” I mentioned above, I noticed some words that reappear in multiple tests, and that many words on the test were in the SAT 2400 book. I mostly focused those repetitive words while studying other vocab.
I have 3 vocab studying strategies: 1, make flashcards and lay them on a table next to your bed and study them right before you go to bed and as soon as you wake up. Sleeping helps your brain organize and memorize, so it’s best to look at the words, sleep and let your brain memorize it, and review in the morning to refresh. 2, this video’s method <a href=“How to learn 50+ vocab words a day - YouTube”>How to learn 50+ vocab words a day - YouTube; helped me a lot since I am bilingual as I think you are as well since you are from Poland. 3, memorize vocabulary in 1 word synonyms instead of long definitions for faster and efficient memorizing.</p></li>
<li><p>I heard that the SATs aren’t offered as many times as in the US in international areas, so it would be best to make sure of those dates and take the tests when you feel comfortable. Take it once after you study a good amount, and when the results come in, focus on the areas you didn’t do as well in so you improve the second time you take it.</p></li>

<p>Sorry about the long post, I hope it helps.
Best of luck to you! (:</p>
