32% students from a class dropped out. 3% of them went abroad. If 60% of them are in probation and the remaining 12 are not in probation, how many students from the class are in probation?

Let's break down the problem step by step.

1. **Determine the total number of students who dropped out:**
   - Let the total number of students in the class be \( N \).
   - 32% of the students dropped out, so the number of students who dropped out is \( 0.32N \).

2. **Calculate the number of students who went abroad:**
   - 3% of the students who dropped out went abroad.
   - The number of students who went abroad is \( 0.03 \times 0.32N = 0.0096N \).

3. **Calculate the number of students who remained (didn't go abroad):**
   - The number of students who remained is \( 0.32N - 0.0096N = 0.3104N \).

4. **Determine how many students are in probation:**
   - 60% of the students who remained are in probation.
   - The number of students in probation is \( 0.60 \times 0.3104N = 0.18624N \).

5. **Determine the number of students who are not in probation:**
   - The problem states that the remaining students, who are not in probation, number 12.
   - The number of students who are not in probation is \( 0.3104N - 0.18624N = 0.12416N \).
   - According to the problem, \( 0.12416N = 12 \).

6. **Solve for \( N \):**
   \[
   0.12416N = 12
   \]
   \[
   N = \frac{12}{0.12416} \approx 96.63 \text{ (approximately 97 students in the class)}
   \]

7. **Calculate the number of students in probation:**
   \[
   \text{Number of students in probation} = 0.18624 \times 96.63 \approx 18 \text{ (approximately 18 students)}
   \]

### Final Answer:
Approximately 18 students from the class are in probation.
