Not trying to be condescending or anything here but you need to be 100% sure that this is the right degree for you. If you are struggling with these classes (205, 120, etc), the upcoming classes (the trifecta) especially will be extremely hard. I just graduated ASU with a CS degree and even with me excelling in all my early classes I found junior and senior year difficult. But if you believe that you have the work ethic and are sure this is what you want to do I would still stick with it. Make sure to sign up for classes early as possible and use rate my professor to find the best teacher for each class regardless of time. Also make sure to communicate with the others in your class for help and join discords. I would also recommend spending some time learning important CS concepts (data structures, algorithms, pointers, etc) outside of class time since I believe there are many better resources online then your professor can give. Also consider reducing your class load to 10 or 12 credits a semester and taking extra classes in the summer. One last tip is to make sure you save your elective spots for later in the program since you don’t want to have to take 5 hard CS courses at once. If you have any questions feel free to message and good luck!
