I’m guessing MechE or ElecE on a strict two year plan?
I’m not an engineer but from a math POV, I recommend taking Calc I over the summer before your first fall semester and moving up Calc II, Calc III, and DiffEQs respectively. Calc II and Electromag are the hardest for most people so making that change would help a lot in alleviating the difficulty surrounding those courses.
Intermediate English(4?) seems like a good choice for the summer before your second year as well, should that be an option, as it allows you to move up Linear and Materials.
I would reconsider the two year plan though as that is a very demanding schedule even with the proposed changes. (Two year Eng transfers plans are really geared for students that have prior credit in Calc and/or Physics.)
