Financial Modelling Classes

I was just reading something on financial modelling classes. Two “well-known” are the Wall street prep and Training the street. Wondering how useful are these classes. As in, worth the money and time? And will it make ur resume more attractive? I don’t have anything lined up over the summer yet, and I graduate in fall. So, is it a good idea to do some self-studying with these courses after my level 2 in june? How do you guys perceive this? Your insights will be very useful. P.S. trying to get into research (equity or fixed income, no preference)
