Can you afford the price of retakes?
If you can, study as much as possible but don't overdo it, you've already failed and doing well in all subjects will stretch you too far. Maybe focus on passing 1 of the 3 courses so you have less retake time.
If you can't afford the retake prices, look online for financial help.
If you are going to drop out, sign up for social security/benefits and start looking for work. Make sure you leave your Uni with a transcript of the existing work you've done as those credits can count towards a degree later in life if you choose to go back into education.
