Produced in situ, it is much more reactive than ordinary H₂. Often used for reductions that standard dihydrogen cannot perform.
Temporary: Ca/Mg Bicarbonates. Removed by boiling or Clark's process (Lime).
Permanent: Ca/Mg Chlorides/Sulphates. Removed by Calgon's or Permutit process.
As exams approach, even the most prepared students start feeling anxious. Heart racing, overthinking, lack of focus — this is completely normal. But the key difference between average and top performers is how they handle anxiety in the final days.
This guide will give you practical, science-backed methods to stay calm, focused, and confident during last moment preparation for exams like JEE and NEET.
Anxiety is your body’s natural response to pressure. A small amount of stress actually improves performance (Yerkes-Dodson Law).
Shift your mindset:
Your brain works best in cycles. Study in focused blocks:
During study time:
If your mind is racing with thoughts:
This clears mental clutter instantly.
Last moment anxiety increases due to external noise:
Solution:
Try this simple technique:
Repeat 5–10 times. It reduces anxiety within minutes.
Most anxiety comes from thinking about results:
Replace with:
Top students focus on process, not pressure.
Last moment is not for learning new topics. Instead:
This builds confidence and reduces panic.
Many students sacrifice sleep — biggest mistake.
Rule: No late-night panic studying before exam.
Start your day with small wins:
This builds confidence and reduces fear.
Close your eyes for 2 minutes and imagine:
Your brain starts believing this as reality.
Anxiety doesn’t mean you are weak — it means you care. The goal is not to eliminate anxiety, but to control it and perform despite it.
Remember: Calm mind + Clear strategy = Peak performance
On exam day, avoid last-minute discussions. Trust your preparation and stay in your own zone.
If your exam is near and you are feeling overwhelmed, don’t worry. The last moment revision of chemistry is not about studying everything again — it’s about revising smartly. In this article, we will guide you through a proven system to maximize your marks in minimum time.
In the final days, avoid opening new topics. Instead, focus on:
Flashcards are one of the fastest ways to revise concepts, reactions, and formulas.
👉 Use: Chemistry Flashcards
They help in:
Revision without practice is incomplete. Solve as many tests as possible.
👉 Start Practicing: Practice Tests
Also attempt full-length mock tests:
👉 Try Now: Mock Tests
Your own notes are your biggest asset during last-minute revision.
👉 Revise from here:
These notes are already filtered for exam relevance, saving you time.
Formula sheets help you revise the entire syllabus in minutes.
👉 Access here: Chemistry Formula Sheets
After every test, spend time analyzing mistakes:
This step alone can increase your score significantly.
The last few days are not about studying more — they are about studying smart. Stay calm, trust your preparation, and focus on revision.
Remember: Consistency + Smart Strategy = Maximum Marks
Revise daily, sleep well, and avoid distractions like social media during this critical phase.
Fill the conceptual gaps between high school and higher secondary. Start your JEE/NEET journey with the right foundation.
Transitioning from 10th to 11th is often the toughest hurdle for science students. This course is designed to introduce high-level topics like the Mole Concept, Atomic Structure, and Organic Reaction Mechanisms in a way that feels natural and manageable.
