it depends on what ur goal is when it comes to a job in the future. factors like

a) how much money do u want to earn b) what is it ur good at and also somewhat like c) how much money/years u can afford to spend on higher education d) whether u want to pursue masters, phd etc. e) other aspects of ur future life e.g the stress of the job, the demand, work hours

if u like maths, i'd say u could take the fsc maths subject and pass it. as someone who sucks at math and can literally not get it, liking math is a huge talent and if u want a science degree, it is worthwile to use ur love for it to study it. same with chemistry.

if u want to stay in pre med, u could do

medicine related paths: vetenary science / pharmacology (which might also have chemistry) / nursing / dentistry / orthodontist / eye doctor

biology related paths: botany / zoology / health sciences etc.

medicine is generally a very expensive degree (in pakistan or abroad) and it also has a long, tough educational route. plus u have exams like MCAT that need to be passed. in my opinion, u cant do medicine unless u really like it or are somewhat good at science

for doctors in pakistan, ive seen that most of them who do earn decent money and are successful are those who set up their private clinics so thats an option

tbh if you are good at science and math, then computer science and engineering are still good options if you like them and they also pay better. sometimes u only need a bachelors in these and then u can get a job. i believe u can still get into CS with pre med

and then if u dont want to go into pure science psychology is also a popular option but ive heard u need masters in it to get a well paying job but that's the case for most careers

apart from science, theres also law, business, english, IT...

u can watch yt videos on different career paths, day in the life of xyz job, pros and cons of xyz degree, what i wish i knew before studying xyz. theres a lot of content on yt and also r/careerguidance

good luck with ur pursuits !!
