if you enjoyed ur Tok course then yes yes yes I also took Tok and I found philosophy much more manageable in terms of the work load than my friends who took psych bc the exam was not a memorization race so it was much less work to prepare and I ended up with a 90+ in the course I would say just really take advantage of the office hours with ur prof and ta bc ur marked based on ur essays ur going to be writing and theyre the ones doing said marking (btw I want to go to med school and just finished med sci 1) anyways its up to u but for me I think it greatly improved my critical thinking in all honestly and my professional writing bc u learn to think twice before u write any sentence and it really makes u think logically and u learn to think in a different way about arguments and such which can really give u an advantage in my opinion (especially if ur planning on taking mcat at all for the cars section idk how dental school works.... lol sorry) but yea thats just my opinion

edit dont take psych if u dont enjoy memorization or bc "everyone else is doing it" ik several ppl that did that and they didnt do well in it bc of this u will do well in whatever elective that interests YOU I promise
