One of the most common points of confusion for Rajasthan LDC exam aspirants is the difference between gross speed and net speed in a typing test. Examiners use net speed — not gross speed — to determine if you qualify. Misunderstanding this formula causes candidates to underestimate how accurate they need to be.
Gross Speed vs Net Speed
Gross speed is simply how many words you type in the given time, regardless of errors.
Net speed deducts a penalty for errors before dividing by time. The result is your actual qualifying speed.
The Net Speed Formula
Net speed (WPM) = (Total words typed − Error penalty) ÷ Time in minutes
Different exam bodies apply error penalties differently. Here are the two most common methods:
Method 1: Word Deduction (most common in Rajasthan)
Each error costs 1 word from your total.
Net WPM = (Words typed − Errors) ÷ Minutes
Example:
- You typed 380 words in 10 minutes
- You made 20 errors
- Net WPM = (380 − 20) ÷ 10 = 36 WPM
At 36 WPM net, you pass the RSMSSB LDC English test (minimum 35 WPM). But:
- If you had 50 errors: (380 − 50) ÷ 10 = 33 WPM → You fail.
Method 2: Percentage Cap
Some exams disqualify candidates whose error rate exceeds a threshold (e.g., 5%) regardless of speed. Under this method, if your error rate is above 5%, your result is automatically disqualified even if your net WPM is above the minimum.
Always read the official exam notification to confirm which method applies to your exam.
What Counts as an Error?
- Wrong character typed (e.g., typing
ainstead ofs) - Extra space
- Missing character
- Transposed characters (
tehinstead ofthe)
Backspacing and correcting a word before the cursor moves past it typically does not count as an error on most software — the final typed word is what is evaluated. However, some exam software does not allow backspace at all. Practise under the same conditions your exam will use.
Worked Examples
| Words typed | Errors | Time | Net WPM | RSMSSB English pass? |
|---|---|---|---|---|
| 400 | 5 | 10 min | 39.5 WPM | Yes (≥35) |
| 380 | 30 | 10 min | 35 WPM | Yes (exactly 35) |
| 360 | 40 | 10 min | 32 WPM | No |
| 340 | 10 | 10 min | 33 WPM | No |
| 320 | 0 | 10 min | 32 WPM | No |
Key insight from the table: fewer errors matter more than typing faster. A candidate typing 380 words with 30 errors passes at 35 WPM, while a candidate typing 340 words with 10 errors gets only 33 WPM and fails.
Hindi Typing Requirements
| Exam | Language | Minimum Net WPM | Test Duration |
|---|---|---|---|
| RSMSSB LDC | Hindi | 30 WPM | 10 minutes |
| RSMSSB LDC | English | 35 WPM | 10 minutes |
| HCRAJ LDC | Hindi | 30 WPM | 10 minutes |
| HCRAJ LDC | English | 35 WPM | 10 minutes |
For Hindi, 30 WPM net over 10 minutes means you need at least 300 net words (words typed minus errors).
How to Improve Your Net Speed
1. Focus on accuracy first, speed second
Most candidates make the mistake of typing as fast as possible and accepting high error rates. This is backwards. At the LDC level, reducing your error rate from 10% to 2% adds more to your net speed than increasing your gross speed by 5 WPM.
Target: Keep errors below 5 per 100 words (5% error rate) before pushing for higher speed.
2. Practice at the exact exam duration
The RSMSSB LDC typing test is 10 minutes. Practice exclusively in 10-minute sessions — not 5-minute warm-ups or 30-minute marathons. Your stamina and consistency at exactly 10 minutes is what matters.
MedhaV.in typing tests default to 10 minutes to match the exam format.
3. Track your net WPM over time
MedhaV.in shows your WPM and accuracy after each test. Keep a simple record:
| Date | Layout | Gross WPM | Errors | Net WPM |
|---|---|---|---|---|
| Jun 1 | Krutidev | 28 | 8 | 20 |
| Jun 8 | Krutidev | 31 | 5 | 26 |
| Jun 15 | Krutidev | 34 | 4 | 30 ✓ |
Seeing the trend gives you confidence and tells you when you have reached the qualifying threshold.
4. Do not skip English practice
Many Hindi-medium candidates neglect English typing and then struggle in the English segment. Both 30 WPM Hindi and 35 WPM English are mandatory — failing either one disqualifies you.
Practice both every day, even if you alternate sessions.
