Biotic Shepard didn't even know about human biotic training academies and implants. How would a human biotic not know about this?
That's like being a Dalish elf and not knowing who Mythal is. Wait. That happened too. Damnit!
To be fair with Biotic-Shepard:
2151 CE Kaidan is born (mother pre-exposed being pregnant)
2154 CE Shepard is born (after? there is a second publicized accident involving the exposure of humans to element zero).
2158 CE Humans learn the potential of biotics. (...) Roughly 10% of recorded exposed children show indications of biotic ability.
2167 CE L-2 biotic implants are first developed and used in humans. Kaidan Alenko is among the first to receive the new implants (he is now sixteen years old, Shepard is thirteen and his/her biotic are not permanent it seems)
2168 CE Kaidan Alenko accidentally kills Commander Vyrnnus. BAat is shut down a year later (2169)
Shepard receives a secondary exposure to element zero. Permanent biotic inclination manifests (Shepard is now fourteen years old)
(source: http://masseffect.wi...m/wiki/Timeline )
So, Shepard uses directly L3 implants. Maybe he or she doesn't know the specifics of the other implants. And he/she was younger than Kaidan so when he or she had the age to go there, it had been shut down already. Also, Shepard was older than other generations which went to Grissom Academy.
Shepard is in a gap of biotic education. My poor child
