Whether you should use SRS for any given domain is completely dependent on your specific circumstances. The answer could easily be different for you and a classmate of yours who fits the description above. But I'd say that if there's some are you'd like to work in that requires specific knowledge that fits well within SRS, why would you not? As opposed to trying to learn and recall anything that might possibly be useful, ever.
