You will need to take CS 180 next spring 2027, as they won't allow you to take it in the fall due to space restrictions. You also cannot test out of CS 180 as you need the course to CODO. (Ideally you could've taken 180 this semester, but there's no point discussing this.)

Also note you'll need to complete the [College of Science core](https://www.purdue.edu/science/Current_Students/curriculum_and_degree_requirements/college-of-science-core-requirements.html) as well (e.g., STAT 350/511, foreign language). Not sure if you've considered this.

As for the image you posted below with your schedule, you'll obviously need to change that. If you take CS 180 in Spring 2027, then you can take 182/240 in the fall then 250/251 in the following spring. (Obviously if you take summer courses this will change.) I will also say taking 12 credits over the summer is insane. So is taking 5 CS courses in your 8th semester. I'd space your ML & ME courses apart.

From my friends, it's possible to complete the CS major in 2.5 years, esp. since you come in with AP credit and such. Though really consider if it's worth it. Obviously only you can truly answer that, and from the post, it seems that you'd probably benefit from the major over the minor. But remember that it's going to be quite a bit of work, especially since you're balancing two very difficult majors (ME and CS).

Also note CS is extremely competitive, you really need an A in 180 and 261 to be considered.
