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

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

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