Question about training

I am going back to school and finally found a BJJ place to train. I am a senior and only have 15-16 weeks of school. They offer Judo classes as well. I am definently going to do BJJ it is two days a week from 6:45 to 8:30. Questions: In 15 to 16 weeks is it worht it. What I mean is will I have acquired a good amount of knowledge.
2) Should I take the Judo class as well?
Thankyou for your help.
