I have researched the different student bank accounts on offer and looked at which freebies/ interest free overdraft would benefit me most. I am not the most financially literate, but I have determined that ideally I want a free railcard (or at least free £100 cash) that's been offered as I will be commuting to London quite often. For context, I will be a first year medicine student going to a London uni, so I am a bit anxious about managing my funds, hence why getting a large interest free overdraft may come handy, especially in the following years of my degree. Ive seen some advice saying that opening multiple student accounts is not wise, as you may end up with a lower credit score and I can understand that transferring money between multiple accounts would be stressful. However I also read somewhere about how you could apply for a student bank account at one bank, claim the railcard, then close the account afterwards to switch to another bank. I'm not sure what negatives could result from that. Any advice? Much appreciated.
