Most US chem programs do some form of:
Year 1- General Chem 1/2
Year 2- O Chem 1/2
Year 3- P Chem 1/2
Year 4- selected advanced classes/electives
Other required classes usually include Inorganic/Analytical/BioChem, taken in any order, generally in years 3 and 4.
I just want to put in one tiny more plug for UK schools. My daughter is a chem major at St. Andrews and I was a chem major at a small LAC in the US and I think you could make it work.
In the spring as a second year she will be taking P Chem 2 and Organic Chem 2. So a US based sophomore or junior, could easily do just those courses as it aligns with the above schedule for spring of a typical US curriculum. Then add in an elective or 2 to fill out the schedule.
