Hi @emirkhalid080798, first thing first, congrats for scoring straight A's SPM result!
There are a few ways to study Medical course, since I do not know your preference, family financial background or constraints etc, I just list down the common paths to pursue a degree in medical related courses.
Local Public University (University Awam)
To get into local public university for degree courses, you will first need to take either Matrikulasi or STPM.
After you have completed the pre-university programme, you can apply using your Matrikulasi or STPM result for admission into medical courses offered at UM, UKM, UIAM etc.
There are quite a number of universities that offer medical courses. Make sure you take biology and chemistry subjects during your Matrikulasi or STPM.
Local Private University
There are a number of private universities in Malaysia that offer medical related courses like International Medical University (IMU), AIMST University etc. Mind you, the fees are really exorbitant.
Again, since those medical courses are degree courses, you need to take Matrikulasi or STPM or A Level first and then apply for admission using Matrikulasi or STPM or A Level result.
Alternatively, you can take foundation courses offered at these universities. For example foundation of science.
You need to take Matrikulasi, STPM, A Level or other pre-u programme first and then apply for admission using the result. Alternatively, you can take foundation courses offered at these universities.
Also, most overseas university will require you to take IELTS or TOEFL as your English assessment. So remember to take that anytime during your pre-university year.
Just in case you don't know, some overseas universities do set up branches in Malaysia and offer medical related degree courses. For example, Newcastle University Medicine (NUMed) Malaysia. So you can study at these universities in Malaysia and get the overseas degree / certification.
