Common mistake: Students split time equally - Physics: 33%, Chemistry: 33%, Biology: 33%. Result: They understudy Biology and overstudy Physics.

Why this fails: Biology = 360 marks (50% of NEET), Physics = 180 marks (25%), Chemistry = 180 marks (25%).

The smart split:

Biology: 40-45% of time (because 50% of marks)
Physics: 30-35% of time
Chemistry: 20-25% of time

This article gives you the exact hour allocation based on your weakness/strength in each subject.

The Reality Check: Biology is 50% of Your Score

Subject	Questions	Marks	Percentage	Suggested Time
Physics	45	180	25%	2.5-3 hours/day
Chemistry	45	180	25%	2-2.5 hours/day
Biology	90	360	50%	3-4 hours/day
TOTAL	180	720	100%	8-9 hours/day

Key insight: Biology deserves 40%+ of your time because it's 50% of marks AND easier to score in (fact-based vs calculation-heavy).

The Dynamic Allocation Strategy

DON'T allocate time equally every day. Allocate based on:

Subject weakness
Exam weightage
Your current score

Scenario 1: You're Weak in Physics

Your mock scores:

Physics: 90/180 (50%)
Chemistry: 130/180 (72%)
Biology: 280/360 (78%)
Total: 500/720 (69%)

Problem: Physics is dragging you down.

Time allocation (for next 2 months):

Physics: 40% (3.5 hours/day)
Chemistry: 25% (2 hours/day)
Biology: 35% (3 hours/day)

Goal: Bring Physics to 140/180 (77%), which adds +50 marks -> Total 550+

Scenario 2: You're Strong in All Subjects (Consistent)

Your mock scores:

Physics: 140/180 (77%)
Chemistry: 140/180 (77%)
Biology: 280/360 (77%)
Total: 560/720 (77%)

Problem: Consistent across all, need to push all up to 85%.

Time allocation (standard split):

Physics: 30% (2.5 hours/day)
Chemistry: 25% (2 hours/day)
Biology: 45% (4 hours/day)

Goal: Focus on Biology (easiest to score), bring to 320/360 (89%), adds +40 marks -> Total 600+

Scenario 3: You're Weak in Biology (Rare but Happens)

Your mock scores:

Physics: 140/180 (77%)
Chemistry: 140/180 (77%)
Biology: 240/360 (67%)
Total: 520/720 (72%)

Problem: Biology is weak (unusual).

Time allocation (heavy Biology focus):

Physics: 25% (2 hours/day)
Chemistry: 20% (1.5 hours/day)
Biology: 55% (5 hours/day)

Goal: Bring Biology to 300/360 (83%), adds +60 marks -> Total 580+

Month-by-Month Time Allocation

Months 1-4: Equal Focus (Building Foundation)

Time split:

Physics: 33% (2.5 hours/day)
Chemistry: 33% (2.5 hours/day)
Biology: 33% (3 hours/day)

Why: You're learning all subjects for the first time. Need balanced coverage.

Months 5-6: Identify Weakness, Adjust

After taking 5-10 mock tests, you'll know your weak subject.

Adjust time:

Strong subject: Reduce to 20-25%
Medium subject: Keep at 30-35%
Weak subject: Increase to 40-45%

Months 7-8: Biology Heavy (High ROI)

Why: Biology is easiest to improve in short time (fact-based, less calculation).

Time split:

Physics: 25% (2 hours/day)
Chemistry: 25% (2 hours/day)
Biology: 50% (4 hours/day)

Expected: Biology improves 40-50 marks in 2 months.

Months 9-10: Weak Chapter Focus (All Subjects)

Time split: Dynamic (based on error log)

Example:

If error log shows: Equilibrium (Chemistry), Mechanics (Physics), Genetics (Biology) are weak
Spend 60% of time on those 3 chapters
Rest 40% on mock tests

Daily Time Allocation Examples

Example 1: 8-Hour Study Day (Standard Split)

Time	Subject	Activity	Duration
7:00-9:00 AM	Physics	Lecture + 30 MCQs	2 hours
9:00-9:15 AM	Break	Tea	15 min
9:15-11:15 AM	Chemistry	Lecture + 30 MCQs	2 hours
11:15-12:00 PM	Lunch	-	45 min
12:00-3:00 PM	Biology	Lecture + 50 MCQs	3 hours
3:00-4:00 PM	Break	Walk	1 hour
4:00-5:00 PM	Revision	Error log review	1 hour

Total: 8 hours (Physics 2h, Chemistry 2h, Biology 3h, Revision 1h)

Example 2: 8-Hour Day (Physics Weak - Adjusted Split)

Time	Subject	Activity	Duration
7:00-10:00 AM	Physics	Deep study + 40 MCQs	3 hours
10:00-10:15 AM	Break	-	15 min
10:15-12:00 PM	Chemistry	Lecture + 25 MCQs	1.75 hours
12:00-1:00 PM	Lunch	-	1 hour
1:00-4:00 PM	Biology	Lecture + 40 MCQs	3 hours
4:00-5:00 PM	Break	-	1 hour
5:00-6:00 PM	Revision	Focus on Physics errors	1 hour

Total: 8.75 hours (Physics 4h, Chemistry 1.75h, Biology 3h)

How to Decide Your Personal Allocation

Step 1: Take 3 Mock Tests

Baseline your scores:

Subject	Mock 1	Mock 2	Mock 3	Average
Physics	110	115	120	115/180 (64%)
Chemistry	140	135	145	140/180 (78%)
Biology	260	270	280	270/360 (75%)

Insight: Physics is weakest (64%). Focus there.

Step 2: Calculate Time Investment ROI

ROI = Potential Marks Gain / Hours Invested

Physics (weak at 64%):

Current: 115/180
Potential: 150/180 (with 60 hours extra study)
Gain: +35 marks
ROI: 35 marks / 60 hours = 0.58 marks/hour

Chemistry (strong at 78%):

Current: 140/180
Potential: 155/180 (with 60 hours extra)
Gain: +15 marks
ROI: 15 marks / 60 hours = 0.25 marks/hour

Biology (medium at 75%):

Current: 270/360
Potential: 320/360 (with 60 hours extra)
Gain: +50 marks
ROI: 50 marks / 60 hours = 0.83 marks/hour

Decision: Invest time in Biology first (highest ROI), then Physics, then Chemistry.

Step 3: Adjust Weekly

Every Saturday: Review mock test performance.

Adjust time allocation if:

One subject improves significantly (reduce time there)
One subject stagnates (increase time there)

Common Time Allocation Mistakes

Mistake 1: Ignoring Biology Because "It's Easy"

The trap: "Biology is easy, I'll study it later. Let me master Physics first."

Why it fails: Biology = 50% of marks. Ignoring it = losing 180 marks (half your score).

Fix: Biology first, always. It's the easiest subject to score high in.

Mistake 2: Equal Time = Fair

The trap: "I'll spend 2.5 hours on each subject daily. That's fair."

Why it fails: Fair != Strategic. Biology deserves more time because it's 50% of marks.

Fix: Allocate by marks weightage + your weakness.

Mistake 3: Spending Too Much Time on Strong Subjects

The trap: "I'm good at Chemistry, so I'll study it more (feels good to get questions right)."

Why it fails: Studying strong subjects = low ROI. You're already scoring high there.

Fix: 70% time on weak subjects, 30% on strong (maintenance).

Subject-Specific Time Breakdown

Physics (2-3 Hours/Day)

Breakdown:

1 hour: Concept learning (video/NCERT)
1 hour: Numerical solving (30-40 problems)

45 min: Concept learning
45 min: MCQ practice (Organic + Physical + Inorganic)
30 min: Reaction mechanism practice (Organic)
30 min: Revision

Focus: Organic mechanisms + Physical formulas.

Biology (3-4 Hours/Day)

Breakdown:

1 hour: NCERT reading (detailed)
1 hour: Diagram practice (draw 3-5 diagrams)
1 hour: MCQ solving (50 questions)
30-60 min: Revision

Focus: Diagrams + NCERT line-by-line.

FAQs

Q: I'm equally weak in all subjects. How do I allocate time?

A: Start with standard split (Physics 30%, Chemistry 25%, Biology 45%). After 1 month, re-assess.

Q: Can I study only Biology for 2 months and score 650+?

A: No. You need baseline scores in all subjects. But you CAN spend 50% time on Biology.

Q: I have only 4 hours/day. How do I split?

A: Physics 1h, Chemistry 1h, Biology 2h (maintain 50% Biology rule).

Remember: Time allocation = strategic, not equal. Biology is 50% of marks. Treat it that way.
