CFA for Transaction Services

hi guys,

i am an accounting/banking & finance graduate and I graduated in January 2021.

i have interned in the audit space (risk assurance and audit) and I find myself quite interested in transaction services, specifically deals and M&A but am finding it difficult to break into TAS.

how beneficial is the CFA if i would like to break into the valuation & modelling department of TAS? on top of that, is it recommended to do the CFI/WSO financial modelling course as well?

thanks a bunch and i hope to hear from you guys! help a fresh grad out yea
