Computer science struggles

im a dp1 student and i decided to take computer science sl. Im currently having a really hard time understanding and learning specifically the coding parts of the subject, i cant seem to learn and i always make mistakes. Ive also not been able to find any resources on the coding part. I got a 1, 4 and 1 in my 3 summatives ive had so far and i am 16 days away from my school exams. Does anyone have tips to improve and learn and understand deeply?
