<p>Basically, I am just looking at what SAT subjects to study and I am thinking of doing US history but I have very, very basic knowledge of US history as I am international student. I'll be studying starting from now and I am a junior. So, is it doable to study the whole content with very, very basic knowledge of it and get a decent 650+ score on it? I will be hopefully studying it for only 5-6months but 1-2 hours a day. </p>
<p>PS, is it ok for me to use this website instead of buying a book or shall I just buy a book? I prefer the website due to me liking typing my notes on the computer.</p>
