How do I get into the Slytherin common room on pottermore if I'm not a Slytherin?

Hmm.. well, did tu try the Polyjuice potion yet? If tu did, then tu might be able to get into the common room por going through the chapter, like tu always do.. (I haven't been on pottermore in forever so sorry if I get stuff wrong) If tu can't do that, then maybe , try and add somebody that's a Slytherin and see if tu can get in then. =/

I don't know perfectly but I've heard that u have to make the Polyjuice Potion........
