<p>The sort of score increase you seek is highly unlikely . . . nothing is impossible, of course, but this is close to it. I would caution you about unrealistic expectations if you had a 26. At this point, do some prep, but don’t set your sights on an implausible outcome. You can certainly improve your scores enough to qualify for a four-year college, but probably will not get them high enough for a college which is notorious for its emphasis on high test scores. Getting your score up over 20 will be cause for celebration. Aim for that.</p>
