First, without the invisibility cloak, levitate the jar thing on top of the bookcase just inside the door. This will cause a disturbance that Snape will investigate. As Harry, wear the cloak of invisibility and go up the steps to the right, behind the bookcases there. Pick up the Key. Snape will move to the steps in the back of the room. Keep the invisibility cloak on and go past him to open the door. You will find the first ingredient in the chest there. Light the cauldron to make the potion on the table blow up (I hid behind the door, but you could leave the room) and when it blows up, Snape will run in the room and drop the key. Go pick up the key and move to the left around the bookcases. Open the next chest. Snape will move to the edge of the bookcases and prevent your escape. To get out of this, move close to the bookcases and see the cauldron on the table on the other side. Light this as well, it will blow up and Snape will move. Run out of the room.

If you get an A (Acceptable) or an E (Exceeds Expectations), or an O (Outstanding), you may enter the Potions classroom.
There is a cauldron on the floor, and there are a few potions on either side of Harry. You use Wingardium Leviosa to pick up a potion bottle whose color matches the color of the potion in the cauldron on the floor, and drop the bottle into the cauldron. For example, if the potion in the cauldron is red, you use Wingardium Leviosa to pick up a red potion bottle, and then drop the bottle into the cauldron.
