Labs take place in 271, 273, 275, and 330 Soda. A cardkey is required for access to the labs and to Soda Hall after hours. If you are a Berkeley student, your student ID card serves as a keycard, but you must apply to have it enabled at 387 Soda or 391 Cory. If you are a concurrent enrollment student, you must pay $20 for a keycard ($5 nonrefundable fee + $15 refundable deposit).
