That makes more sense I think that 300 level was our lowest biochemistry class as well

Maybe our universities handled numbers differently but 300 level classes we’re never considered intro level classes but were instead classes usually taken in your 3rd year of school with a heavy amount of pre requisites and a 500 level would be a graduate class

I had to take a 300 level biochem class and 2 semesters of O Chem and we didn’t have to memorize the structures of all the amino acids. Like we had to know glycine and we had to know about the different amino acids like how proline has a rigid structure but we were never expected to be able to draw an amino acid from memory
