This post assumes you're in NY. If you're not ignore it.
If you're interested in going to school to be an actuary and need to take night classes only, you can do that at Touro. You can definitely do it at the Flatbush campus and probably at the Queens campus (Landers). You can get 48 credits for yeshiva, leaving 72 in class. 12 credits a semester plus 6 in the summer is 30 a year, a total of 2 and a half years. Their program is actually better designed for aspiring actuaries than the majority of colleges. For example, in Brooklyn or Queens College the program is first and foremost a Math major and secondarily gives you some preparation for actuarial exams. In Touro, the classes are very much structured around the actuarial exam process and directly prepare you to take the exams, which are central to obtaining a job as an actuary.
Touro is also very good for accounting, so if these are your 2 choices and you want to do night school, Touro is definitely a good fit.
Both actuarial work and accounting would probably be considered by a lot of people to be boring, so it really depends on you. There's an exam process for both, but they're very different. In general actuaries probably have a higher average salary, but the exam process is longer and in some ways harder. There are many types of specific jobs in both professions.
If you have more questions I'll be happy to try to answer them. I'm not as good at summarizing the whole thing so specific questions are good.
