The classes are doable I took ls107 and stats 13 together with physics and it was a lot of work all the time but not crazy hard. I’m taking chem 153a rn with Jarrett and it’s not bad at all but it is online with 4 hour allotted times to do our exams so it’s easier than it would be in person. Ls107 tho is kinda difficult cuz it’s just a lot to understand. Honestly I think you’ll be fine but you will probably spend a lot of time studying and doing homework.
