The IB Vine technical prep is beyond helpful, it's so much more fun quizzing myself every now and then vs. reading through the guides again.

Check out IB Vine, specifically the 'IB Vine Select' questions. Once you can get a handle of those, it seems like you are in a spot where you're applying the concepts rather than simply memorizing them

Beyond the 400 questions guide, try to understand a deeper level and the underlying concepts of the questions being asked. Use ibvine, it really helps.

IB Vine has excellent questions, especially multistep ones. In my experience I've gotten grilled on accretion/dilution, bond math, and merger model questions. IB Vine has great practice for all of those.

As a nontraditional transfer student who has been rendered unavailable to many resources at my university (Leadership positions at clubs, immediately behind the recruiting cycle, etc.) IB Vine has been an absolute game changer in my IB prep.

From my experience interviewing FT for IB, it’s not enough to just know the 400 questions anymore (it’s a good starting point) but to look at even more advanced questions. Would recommend IB Vine.

Just got off the phone with a kid who interned at a Dallas PE firm. He mentioned that IBvine.io helped him secure that internship as well as his Summer Analyst offer, especially since he came from a non-target with no resources.
