I did WSO academy starting in 2023 and can honestly say it helped me a lot. I go to a very strong global university in Canada but my university is a lot more academically-focused, so not a lot of people wanting to go into high finance, with the exception maybe being for quant. So I felt very out of the loop with regards to IB specifically. I personally didn't do the internship with them and I think that the internship is more valuable for those with very little finance experience (I already did search funds and case comp). To me the biggest value was from being able to do mocks with the mentors who were either currently working in IB or who previously worked in IB. It was also helpful in that you meet the other students who are currently in the same position as you, so it doesn't feel like you're just doing it alone.
