<p>@XCyoungX: yes, you can declare during the summer. The process may take longer but you will be in the major before fall semester starts, and will be given special consideration when it comes to waitlist during the Fall’s adjustment period.</p>
<p>@fl1p: It’s actually normal 61C, with one project omitted (Hadoop MapReduce). (But 3 projects in 8 weeks still takes a ***** ton of time, esp. when 61C is far less trivial than its two predecessors.) 61CL has not been offered for a long time. Yeah, I would say just keep the internship and proceed as you planned, and wait for an announcement to be made, or your grades from EE42 and CS70 this next semester. 10 Evans (the room for Summer’s 61C) has way more seats than just around 100, they can easily expand as long as they can find enough TAs to run the sections.</p>
