I had no problem finding my last one . i just did two sweeps of every location , one at night and one during the day . <| sep |> Calc 2 is twice as hard as calc 151 for me it was 135 is not 151 it ' s easier . Data structures and 111 don ' t even compare data structures is super infamous for its difficulty , 111 is the easiest cs class bio 1 is also a lot easier than bio 2 unless your really good at memorizing . the first exam was almost all taxonomy if I recall correctly . I never took expos . Chem is easy under the condition you invest time . The way your schedule is kind of removes a lot of spaces to really drill and memorize what you need to for exams . If you cant rearrange your schedule to at least have suitable time to study , you will screw yourself over . Thats why if i were you i would drop bio and take it over the summer . Yup , I ' m premed .
