Most students fill their CSAB choices based on gut feeling. That creates avoidable mistakes because the allotment system always checks your list from the top down. Your order matters more than most students realise.
Fill what you want, not only what you expect
The algorithm checks choice one before choice two, then continues downward. That means your top positions should hold your best realistic outcomes, not only safe seats.
If you place a low-value safe choice too high, you can lose access to a better option that should have been above it.
The 3-tier method
- Reach choices Put options slightly above your current cutoff comfort zone near the top where upside matters most.
- Target choices Use the middle of your list for branches and colleges where your rank is comfortably competitive.
- Safety choices Use the lower part of the list for options you are highly likely to get so you do not end up seatless.
Use round-specific data
A college that looks out of reach in Round 1 may become realistic in Round 2 or Round 3 as seats open up and withdrawals happen.Branch vs college: what should come first?
- For CSE and IT careers, branch value often matters more than institute prestige.
- For core engineering, institute quality and placement ecosystem often matter more.
- For IIIT-focused tech goals, a strong IIIT can beat a weaker branch fit at an NIT.
What not to do
- Do not leave large parts of the list empty.
- Do not put a safe choice first just because you are nervous.
- Do not ignore strong GFTI options in your safety layer.
- Do not rank primarily by city if branch and institute fit are weaker.
