Summer section eats into my lecture?

<p>Soooo. They just changed the UGBA 103 section to WF 8-10.30, which ruined my wonderful plan because it now eats into my Econ 100A lecture which starts at 10. Does it matter? Can I just leave discussion early to go to lecture (or leave later and arrive at lecture later...except for exam days)?</p>

<p>If nothing else, it would matter for midterms.</p>
