Hello advice needed ! i'm new !

Hi, there everyone I am new to the WSO forum. A bit about me. I am living and studying in London currently at a target business school called CASS business school and my degree is in Investment and financial risk management. I have just completed my first year of studies however my final exams got canceled due to corona. I decided to make a WSO account because I have 0 ideas of what to do career-wise. our university teaches us a lot of stuff but does not delve too much into the different types of sectors etc (i assume they were going to do that this term lol)

So essentially I have 3 main questions to ask you guys today, as I am sure you're much more knowledgeable than me. So essentially the idea of IB / PE / HF / VC all appeal to me actually and all seem interesting in their own rights, however, private equity seems to interest me the most. Unfortunately, I have heard it is very very very very x10^27 difficult to get into and so usually they don't hire from undergraduate but rather just recruit from people who have done the IB analyst program. Since my business school and course, in particular, are quite good at churning out graduates that land roles at IB analysts especially banks like GS, JP Morgan, Morgan Stanley, etc, I was aiming to go to one of these.

My first question is how do I go about getting an internship next summer? I already jotted down some ideas such as do insight days, insight weeks, show them my track record for trading as I do some trading on the side as a hobby. I also just done a few excel/python courses online. However, I still feel these are not enough for the IB internship at a BB IB. any suggestions to land that second-year internship at either a PE or IB firm - should I do a course in LBO models?

My second question is regarding what to do after my undergraduate. do I pursue an MBA and do a CFA as well. or should I do something that's more in 'modern' such as a computational finance masters /data science masters that incorporate algorithmic trading / R as well as stochastic financial modeling methods and do this with a CFA? I know I'm young and stupid so what I might say next is controversial but MBAs seem overrated to me. it's literally just the first-year content of a management/finance/accounting/econ degree stuck into one year but banks and PE and Hedge funds seem to love them a lot.... so TLDR MBA + CFA or data science/data analytics + CFA.

My last question is, what if it all goes to shit... say I don't do as well as I have been doing and something terrible happens to my grades and I get a 2:2 in the future. is there a way to get into IB from a different job? what other types of jobs are out there that are not PE / HF / IB that are lesser paid but can be a 'springboard' so to speak to eventually get into IB etc. I know someone that got into Goldman after working for a long time at Deloitte. is this common?

Sorry for the long post, but thanks for reading it all
