This kit is for both General Physics 1 and 2 if taken online (PHYS 1401 & 1402). We recommend only purchasing the DUAL kit if you plan to take both courses within the same semester. This is a lab kit access code and will be EMAILED to you, which you will redeem for the physical lab kit. Once redeemed, the kit will be shipped to you from the distribution center. Order ASAP – can take 5-10 business days from redemption date to receive the physical kit.
