I have low A level grades and PH website says they look for majority As in A levels. Will it make sense to apply?
Depends on how low it is and If you have mitigating circumstances. Always check with grad recruitment if you're unsure. But if it says majority A, I (personally) wouldn't apply with something less than AAB. Based on what they say.
There's no shame in applying, just know what you're up against and what you have to do to make yourself stand out - Top Degree grade, work experience, strongly written application, etc. Your materials have to be strong IMO. Maybe that could get you through!
But also just a question, why Paul Hastings? (I assume it's them). I'm sure you could get accepted by another firm that's less strict on grade requirements. I'm sure it's a great firm but there are so many other US/UK firms to consider. Is there something exceptional about the firm that makes you believe you SHOULD apply? Particularly when you know you don't meet the requirements? I hope I'm not sounding too harsh or direct. I'm just as curious as you are.
