Analyzed the graph sequentially by universities and added the count of repetitive ciphers. May be university prioritization and then matching ciphers with the rest might speed up the process like if we just check Pigpen and Scytale Ciphers as they are quite top on the list, it allows us to narrow down the university to Seton Hill University and Jefferson Wheel can then be added to the list.

Let me know if anyone else figured out a faster parsing process.

IMO: (3, Seton Hill University)

Ignore universities, first look for cipher names that appears more than one times.
I. Pigpen
II. Scytale
III. Jefferson Wheel

Now look for the university that teaches all three.
-> Seton Hill

Since th eproblem asks for universities, it would be faster to see the universities first. Take the one having the max no.of courses obviously for the best chances and it leaves us with last 2. Quick few seconds glance and we find Seton Hill having quite a few similarities. Now we can fix this to be the univeristy and on back tracking finding 3 as the most from seton is straightforward.

i just listed down the common techniques in all the available colleges. and then in those how many of colleges are in each of those technique.

pigpen - johns and seton
