This is an original preparation plan, not a new examination announcement. Check dates, stages, eligibility and application instructions in the issuing authority’s current notice.

Plan your preparation
Use a short daily scan drill with a deliberate token filter. Review errors by recreating the exact counted subsequence rather than simply noting that the final answer was wrong.
02 / UNDERSTANDING
The concept in context
An alphanumeric series combines different token types in one sequence. First identify what the question calls a letter, digit or symbol, then apply positional conditions exactly. The third digit from the right refers to the order of qualifying digits, which may differ from the third token from the right in the complete sequence.

A worked learning case
Original educational case. In the original sequence A 4 # B 7 C 2 %, the digits from the right are 2, 7 and 4. The second digit from the right is 7, while the second token from the right is 2. Deleting all symbols gives A 4 B 7 C 2, which has a new six-token position structure.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Original practice: In M 8 @ N 3 P 6 &, which is the second digit from the right?
Show the answer and reasoning
3.
Ignore letters and symbols for the requested digit count. Reading qualifying digits from the right gives 6 first, 3 second and 8 third. Therefore the answer is 3. Counting all tokens would answer a different positional question, so filtering by token type must happen before assigning the requested rank.
Two traps to watch for.
- Counting all tokens when only digits are requested.
- Using original positions after deleting or rearranging tokens.
