DCS RankWhat it is
A low score in a chapter only matters if that chapter shows up often in the exam. Weak Topics combines your accuracy with each topic's exam weight, so the list is ordered by how many marks you're actually losing — not just where you feel weak.

Where to start
Electrochemistry is your costliest gap — low accuracy and high exam weight.
Fixing the top two topics is worth more marks than the other three combined. Start at the top of the list and work down — the bars rise as your accuracy climbs.
How it works
1
Break down by topic
Every question you attempt is tagged to a specific chapter and sub-topic.
2
Score accuracy
We calculate how often you get each topic right, across all your attempts.
3
Weight by exam value
Accuracy is multiplied by how often the topic appears, so big-ticket gaps rise to the top.
4
Rank the list
You get an ordered list — fix the top, watch the bar climb, move to the next.
What you get
✓A precise list of where to start, not a vague “study more”
✓Topics ranked by marks lost, so the costliest gap is first
✓Accuracy bars that climb as you improve, for real motivation
✓A list that re-orders itself as new mocks come in
