Is April too late to start past papers for a level bio and chem?

Hi
My a levels are in 10 weeks I'm a chronic procrastinator and suprise suprise I'm so behind on revision and starting it now . I am trying to understand the content but it looks like its gna take me so long. I have started topic exam questions for mid units and blurting just a couple days ago . I feel like I need to know and understand the content before doing past papers. If I follow this I doubt I'll do past paoers until early April and that's if I only just go over weak topics so if I start past papers i won't have full knowledge. Chemistry my biggest weak topics is module 5 physical physical but with bio I feel like everything is a weak topic and understanding it all might take long and even if I do understand the content when I attempt questions I still get it miserably wrong. To any past or current a level student is starting past papers in early April too late because I know people who stared in February and ik it's my fault. Plus does anyone have any tips on how to go through pats papers like what should be the method to make it efficient as possible.
Thanks

I get you, i'm similar, look at me on TSR giving other people advice that I don't take myself but whatever
I don't know about biology but with chemistry I use a youtube channel called allery chemistry and he's really good, watch his year 1/year 2 playlist, they are long in total, but each video is like 20-30 min, so not that long.
I think it'll help you a lot, I would have failed the March Mocks if i hadn't had him, so try him out.
Good luck to you and us idiotic procrastinators who know we're at fault

😭😭😭nah cos I do the same thing I can give advice to everyone but I don't follow it . I'll deffo check out those videos thank you so much . Would you say it's better to understand the content before doing past papers or starting straight away ??
GOOD LUCK
