I understand completely.
I spent two and a half years at a different college than the one I’m at now studying English, linguistics, psychology, physics, and French (at different times, but I usually double-majored. I changed my majors around 7 times in two and a half years!). God gifted me with abilities in a hefty handful of areas, and I couldn’t decide what I wanted to do. So eventually, I realized I needed to turn it over to God, and with prayer, I discerned that I needed to leave that college and transfer to where I am now and study computer science. (I’ve been here for a year and a half now, with the same major, and I haven’t looked back. So no, it’s not just a fluke. I graduate in May, after only two and a half years. God willing.)
I’m not really sure what God has in mind yet, but I’m confident that this is His will.
Recently, at a group I’m in at my parish, the leader of the group mentioned being at a talk where the speaker said that you don’t discern for the future, you can only discern for today (or, well, the more immediate future). This may or may not be true–probably true in some cases and not in others–but I think, with prayer, you can discern the best field for you and trust that God will provide opportunities for you to use your knowledge and training in the field to serve and glorify Him, even if you’re not exactly sure where you’ll ultimately end up today, before you even begin.
But also, don’t feel like uncertainty or a major change are bad things. God’s paths are not always as straight as the paths of the world. Just because you don’t get a degree in an area doesn’t mean God didn’t want you to have knowledge in the field.
As far as Calculus II goes, if you choose a field that requires that you take it, just
do your homework. If you don’t have homework but you are provided with practice problems,
do them, and if you don’t even have that (doubtful),
do problems anyway. The first time I took it, I didn’t do the practice problems, and I had to drop the class (cue a major change from physics to French). The second time around, besides the fact that my professor was very good the second time (my first professor was confusing), I did practice problems until I understood the concepts and asked questions when I needed to. (I got an A. And the class wasn’t really much easier. I just had to work harder.) I think it’s the same with any challenging class, or any class at all: prepare appropriately, and it shouldn’t be a problem. Some classes just require more preparation and study than others.
I hope you discover God’s will for you soon. God bless.
