Look at any undergraduate course curriculum at your university of choice and just follow that. Some of them might even have lecture notes and exercises published.
As a maths undergraduate, I attended around 10 classes per year - you go see who the instructor is and then just read the lecture notes at your own time at home. Then go take the exam at the end and that's it. That sums up my 3 years of undergraduate studies.
Mathematics is well established, essentially has been frozen at undergraduate level for 50 or more years, so there is plenty of material. Also, you don't need any equipment, just your own mind.
In my opinion, it is the easiest major of all if you can follow the logic. No essays to write and no projects to do - just read the material.
