Should I retake SAT Chem in June?

<p>I just took the SAT Chem and I ended up not doing 15 questions because I ran out of time. I probably missed 10 more. Should I cancel my score?!?!</p>

<p>I'm going to retake it but I don't know when...I was planning on taking SAT I in June, but should I retake SAT Chem instead and take SAT I during October?!</p>

<p>Please help!!</p>
