You finish an evening of revision and, by morning, cannot say what you actually got done. A study journal helps with that, if it stays small enough to keep going until the exam.
Should you keep a study journal while preparing for exams?
Yes, as long as the journal makes you think rather than just record. Researchers at the University of Freiburg ran two term-long studies of university students who wrote regular learning journals (Nückles, Hübner, Dümer and Renkl, Instructional Science). In the first half of the term, students prompted to organise the material and check their own understanding learned more than students writing without prompts.
There was a twist. Once students became skilled journal writers, fixed prompts started to get in the way, and by the end of term a group whose prompts were gradually faded out did better than a group whose prompts stayed fixed. So use a short structure to build the habit, then loosen it.
What goes in a five-line study journal?
One line each, written at the end of your last study session of the day:
Did: what you actually did, in specifics (chapter, exercise numbers, time spent).
Learned: one idea you can now explain, written from memory with the book shut.
Mistake: one error you made and why it happened.
Question: one thing you still do not understand.
First task tomorrow: the exact thing you will start with, and when and where.
Line 2 is closed-book on purpose. Students who practised recalling a passage remembered substantially more a week later than students who reread it, even though rereading made them feel more confident (Roediger and Karpicke, Psychological Science, 2006).
Line 5 is a plan with a when and a where, which psychologists call an implementation intention. Across 94 independent tests, implementation intentions had a medium-to-large effect on reaching goals (d = 0.65) (Gollwitzer and Sheeran, 2006).
It may also help you switch off. In a sleep-lab study of 57 adults aged 18 to 30, those who wrote a to-do list at bedtime fell asleep about nine minutes faster on average than those who listed tasks already finished (Baylor University summary of Scullin et al., 2018). It was one small study, so treat that as a bonus.
What does a real entry look like?
Here is one from a Class 12 student preparing for JEE Main, on a Tuesday:
Did: NCERT Class 11 rotational motion examples, then practice questions Q1 to Q12 from the exercise.
Learned: For a body in equilibrium, the net torque is zero about any point, so I can pick the point that removes the most unknown forces.
Mistake: Q7, I used the moment of inertia of a rod about its centre (ML²/12) when the axis was at one end (ML²/3). Cause: I did not draw the axis.
Question: Why does friction do no work on a ball rolling without slipping?
First task tomorrow: 6:30 am at my desk, redo Q7 from a blank page, then Q8 to Q12.
The mistake line names a cause, not "silly mistake": a cause is something you can fix. And it is fine to end the day not knowing something, as long as you write down what.
How do you use the journal at the end of each week?
On Sunday, read the week's entries together:
Sort the mistakes into concept, method, calculation slip or misread question. The biggest group tells you what next week needs; you can also ask AI to find patterns in your mistakes.
Close the questions. Take each one to a teacher or a friend. For concept gaps, the Fermi Concept Library has a lesson for every concept in physics, chemistry, biology, mathematics and computing.
Practise the method you got wrong. The Fermi Problem Library has worked problems with a step-by-step solver that explains the reasoning rather than printing an answer.
Test the "learned" lines. Cover them and explain each idea again, using the blurting method for revising from a blank page.
Weekly tests? Fold them into the same sitting with this guide to reviewing weekly test mistakes with AI.
What if you miss days, or it starts to feel pointless?
Missed a day? Write tonight's entry and move on; do not backfill. Once the five lines feel mechanical, drop the labels and write freely, keeping only the mistake and the first task. That is the kind of fading the Freiburg researchers found useful.
Parents: the journal belongs to your child, so read it only if invited. A better question than "how many hours?" is "what was on your question line today?"
Tele MANAS is open round the clock; details are on the official Tele MANAS website.
Start tonight: five lines under your last page of notes, and your first task waiting in the morning.
