A level revision advice needed please 🙏

Hi ! I’m really stuck on revision and so was just wondering if anyone could help . I do biology and chemistry which start on the 7th of June so I have about a month till exams. I’m really weak on quite a few modules however I’m not going to have time to go over them all before my exams . I don’t know whether it would be better to just focus on the paper 1 modules and do the paper 2 in between the exams or whether I wouldn’t have enough time/ it would be too stressful . Please let me know what you guys would do I’m aiming for A’s but I’m so stressed aaaaa xxx

i'd recommend spending a week going over your weak areas - use your school rev guide as they're quite detailed and have practice questions so you're getting 2 in one if you get what i mean.. for chem especially i'd say you need to put more effort(and practice q's) cause the grade boundaries for bio are low but chem is the monster !!
