Help needed with Endings 33 and 37

[PengiQZ]

I am having so much trouble trying to get these endings - I can't get my grade high enough on the berserker route to get ending 33, and when I try to get ending 37 I end up on the Net Bar routes (endings 44 to 49).
I have followed the guides that are up but I'm still not having any luck getting on the routes. I am managing to get on the berserker route but can't get my grade back up high enough after the first simulation test where you fail, and I am managing to become physically weak, have very low health points and have low ideal for ending 37, but I still end up getting other endings. Do you have to choose particular dialogue choices? How high or low do you have to have particular stats? What is it you have to do to get these endings?
Thank you! :)

Ending 37: Traffic accident! You need bad result on the firts mock test, low ideal, little phisical resistance and need to quarrel in the date with Muxin, then you need to go to the Park on weekend and there you suffer the traffic accident. No variations, just one ending. ♥♥♥♥ Luck!
