Put some into savings. Most should go back to the bank to lower your principle balance. Don't invest with borrowed money - ever.

an emergency always happens,,, always

keep it locked away in savings without touching it

everyone should have 5 months of income in savings unless they can count on their parents in case something happens.

Hello, I started high education Aug 2013, and I have in my account ￡3500 (about), which i'm not going to use because I have a part-time job which which I get pay for all things I need to pay.

Should invest ￡3500 or to play safe invest only ￡1750?

Can I lose my money, if I invest?

Furthermore, I have ISA account (saving account) and on it I have ￡800, but only goes up each month less than ￡1. Which is about nothing.

Is it worth to invest?

And which bank as the best interesting?
