Advice for Bachelor Student

Hello, Im planning to go to sweden for uni in autumn, i had a few questions maybe somebody could answer from experience: - Should i already start looking for housing now or do i still have time - If im willing to pay a bit more like 600-700 euros in rent, do i stand a chance at getting a bit bigger place with kitchen? - Is living alone as a stundent from eu in sweden a bad idea --> go find roomates or smth?' - If i practice swedish with duolingo and will take mostly any job offer, can i get a part time job somewhere - Can i get the CSN if im from eu and work the 10hrs or is it really complicated

if anybody has experince/answers, please feel free to comment, thanks!
