Academic Help Needed

Hello Seniors I want your guidance for My second Semster , Currently I had A5 pool in first year I got decent marks in mst (above average in each subject except env) now est results are out and was shocked to see my marks in est especially in electronics and electrical got around 52 total in est got very less in est and c also I expected good marks but got very less in practical 22/30 even though I knew the code for practical . Now I am very demotivated as I will be getting around 7.2 cgpa in 1 st sem but I had expected more but got less in 2 subjects(ee and c) now I am confused wether should I give summer semester or I should improve my score in subsequent semesters . I know my mistakes as in ee but I didn’t focus properly after my mst , I am ready to improve , Please guide me how should I go Will be really helpful
