I am disappointed with the SFSU bookstore. I went to the bookstore to buy a Scantron sheet for my final exam in Spring 2016. Whether I went there in the morning or at noon‚ there was always a long line in front of the checkout counter. I spent at least one hour to buy a Scantron sheet. I really hate to waste so much time in line. There are two checkout counters on the upper floor‚ I couldn’t understand why they just used only one counter. I suggest you buy a Scantron earlier. Moreover‚ I am not satisfied
