<p>I am currently writing a SOP. I worked in 4 labs during my undergrad (including summers). Should I talk about all 4 experiences? Or is that too much? They were all pretty good.</p>
<p>It depends on your statement of purpose’s length, and the kinds of experiences they were and how related they were. If you are allowed 1,000 words or there’s no limit, you can briefly touch on all of them. If you only have 500 words, you’ll probably have to pick 2 to focus on.</p>
