Opinion on changing optionals after 4 attempts. (PSIR->)

just as title.

Context in brief - 4 attempts, 2 Mains,
PSIR too large, theoritical, dynamic, lengthy, fetching low marks even with max effort due to high competition and difficulty in standing out.

thinking about -
Pub Ad (being shorter, PSIR overlap so less time to cover, Less competition...)
Philosophy (mostly for being the shortest and least dynamic explicitely...)
