NCTC

Stuck, What to Prepare first???

Ali Abdullah shares some helful tips for breaking the ice and preparing for Chemistry NSTC Screening Test and tips for better understanding of stuff

NCTCJun 27, 2026Pakistan Olympiads Editorial Team

So, you have registered for NSTC. Yayyy, now its beginning of your ambitious journey towards Chemistry Olympiad and representing Pakistan at International stage, maybe even have a lil.fun there. Wait, that's a long fetch soo we should focus on immediate goals rn, Shall We:

Every journey begins with getting relevant information about the destination. Soo for chemistry, we need to first know What the hell is a Periodic Table and why is it full of these Withcraft Symbols and numbers.

The Numbers Mason, What Do They Mean?!

(Extra points if you got the reference)

Actually, we need to first understand the need for arranging the elements and all that triads, octaves and Mendeleev Guy lore. Its IMPORTANT, not only because they want to force history down your throat but because all those points noted by every scientist helps in contemplating the multi-dimensional nature of our Periodic table and connect the dots.

Note: Everything you need to study will be limited to 11th Class Fsc Syllabus. Also, try to research as you can find the stuff easily on the web, research is staple food for a scientist brain. So, RESEARCH. I believe you can find better stuff on internet while researching for a topic and enjoy it more.

After this, we head over to the smallest stuff (according to our pov), ATOMS. Try to feel why atomic size, E.N and other properties are effected across the whole periodic table. Try to look into outliers behaviours as they challenge our mental models. Then increase the scale to molecules and bonding stuff. See where I am heading, step by step approach.

Then work out with Stoichiometry and I mean to really work on it and try to understand and reason stoichiometric calculations. Practice and then it will seem a piece of cake for you. Work with Elemental analysis and get a gist why we tend to involve in all of this stuff.

Then we can head over to gases and their laws, different properties of gases and diffusion-effusion stuff. Technological aspects of gases properties and how filters, concentrators, refrigerators and other machines utilize gas properties. Meanwhile:

Pss.... Diffusion is used to enrich ahem.. ahem.. isotope. Anyone who sends me calculations and data of that process and technical stuff will be titled APEX SCIENTIST.

Now we know everything about gases so we can again head over to stoichiometry and connect some chemical kinetics with it. Basically, visualizing chemical kinetics for gases is tad bit easier. Just simple stuff like Kp , Kc and Le Chatelier Principle.

Now we need to cool down and condense into liquids and focus on them. Make some lemonade, hey! It's a solution. SOLUTIONS!!! Molarity, Molality, Normality and all these shenanigans need to be dealt with and Beware, don't mix them up as its critical in Medical field. Don't wanna administer wrong drug concentration to a patient.

Dont forget the pH of the lemonade. Btw What's an acid? So take a dive into acids and bases Don't try it as you'll probably burn

With liquids we need to now deal with temperature, heat and sprinkle little bit of Thermodynamics. Thermodynamics is core of Physical chemistry and pretty cool if you look at it from explosive side. Heat, energy release from reactions, enthalpy, entropy and rabbit hole into heat death of universe...

No!, not that far. We are still alive. Thermodynamics should be connected in your mental model with every field of science and chemistry as examiners love to mix stoichiometry, thermodynamics and slap in some kinetics.

Who forgets electrons. Introductory Electrochemistry is a must as it bridges Inorganic, Organic, Physical Chemistry and is pretty easy at this scale. Just general chemistry level Electrochemistry, no Nernst Equations and membrane stuff.

Now, ORGANIC CHEMISTRY. You should just get a small small intro of Organic chemistry as it isn't that much in Screening test due to it being taught in 12 Class in Fsc. (O level students: Surprised Pikachu face)

If you can find extra time, you can look into Science Chemistry youtube channels like Legendary NileRed, NurdRage, Ex&F, Thyzoid and many more. Also find Pop Science stuff like Solar cells, Semiconductor chemistry, Textile, Baking, basic biochem.

Hope I have covered Everything, if there's something missing you can ask me anytime.
