Advice on Rec Letter------Can I just use the generic one?

Hi friends: My undergrad institution decided to give an extended ddl for the law school fall entry. I thought it worth a shot. The problem is that I really had trouble with getting my rec letters, I am super super stressed out abt having to zoom with my professors and talk and negotiate. I do have two/three rec letters from previous school year that I got for some business ma degrees and I knew they're super generic but they're supposed to be talking good stuff about me.

My question is how much it would hurt if I just use the generic ones that may talk some random stuff like "quant skills". If I use them instead of seeking new ones, I believe I could use that energy/stress into getting my LSAT up for like 5 points. And after all i have no idea what my chances are as it's only one school and I haven't taken LSAT yet and I will only have one shot in July before the ddl.

Thanks so much for your advice!

(Edit: it’s a pretty decent school and it seems that it’s gonna be less competitive this round since it’s only for class of 20 here). I do realize that it’s better to get new ones, but I don’t have my ps ready and the deadline’s in a little more than a month, and I think it’s better if I send in the requests now. What should I provide in lieu of my ps?
