HOW CAN I GET GOOD CREDIT FAST HELP?

I have bad credit 535. When I was young 17 or 18 I got a credit card & it’s in collection. How can I raise my credit? I heard only way is to get a credit card? How many points would my score go up if I get a credit card? I was thinking pay my market , food, other store expenses with my card and pay it off in cash. As either way weekly when I’m paid I go to the stores to buy my weekly nesseties , toiletries and food in cash.
can my bank tell me which credit card is good for me and which one will help to raise my credit score?

is there a way get my score up to 650 by March April 2023?
