Discouraged by my MCQ average

I’m a retaker and feeling discouraged by my average being sub 50%. At the point, especially with me retaking, it feels like I should be doing much better by now but I can’t quite figure out what I’m doing wrong.
Decided to completely review each subject, 1 subject every 2 days.
Will report back my findings.
It’s just very stressful feeling like I’m starting back at zero.
