Hi gy!
I guess your question depends on how much chemistry you can handle. CHEM 230 is definitely an intense course, where the workload consists of watching lectures outside of class and the doing problems in- class (it’s a flipped classroom setting). I’d say that it is more application-based in nature but requires a decent amount of practice to know when to use what equations and how to go about solving the problems that Gottfried will ask. CHEM 245, on the other hand, I found to be a more memorization-heavy class which absolutely requires reading the textbook. It introduces a lot of real-world applications of chemistry, most of which were new to me, whereas CHEM 130 may be an easier choice depending on the amount of chemistry knowledge you have before taking the class (it covers general chemistry rules). With all of that being said, I don’t think it’s the worst idea in the world to take CHEM 230 and 245/246/247 together since they’re very different in nature, thus it’ll be harder to get confused by the different concepts. However, it may be more enjoyable to take one of the BMS electives which are memorization-heavy with CHEM 230 than taking it with the 245/246/247 sequence (I’m personally really enjoying MCDB 422). 
 
I hope this helps!
