How to boost scores significantly?

<p>I did my SATS in May last year just to gauge myself and I will be re-taking it in June this year.
Am currently getting around 1.9k, scores range btw 600-680 for all 3 sections.</p>

<p>Currently, I am studying vocab words, grammar, and reading up on essay topics in addition to 3-4 practice tests a week, and reviewing qns i get wrong. </p>

<p>Will be going for a prep class beginning in Apr. Should i continue my current routine?</p>

<p>What are some tips on improving my score to 2200<2310?</p>

<p>I think you should look through this</p>
