you will realize, that learning for the license won't give you any useful knowledge. especially in regard to SDR. unfortunately the exam is very outdated and besides useless stuff like learning ITU prefixes, you will be bored to death while learning e.g. the circuit scheme for a highpass filter.
consider that if you want not to participate in stupid dx contests and prostata talks anyways, but want to do digi modes, packet radio and experimental radio in general, you really do not need a license. nobody cares for you having a license but that old ham boomers. do not talk to them anyways, they are unbearable.
