<p>Teacher recs can be from a teacher from my senior year correct? Just asking to be sure.</p>
<p>Ideally, a teacher rec should come from someone who has had at least a whole year with you. That's the only problem with using a teacher from your senior year (assuming you haven't had the teacher in prior years). IMO, the very best recs are from teachers who have taught you in more than one course.</p>
