Practicals
Overview
Practical sessions allow learners to build, test, and troubleshoot digital circuits on breadboards, reinforcing theoretical concepts. Hands-on activities include constructing logic gates, flip-flops, counters, and a final integrated project, developing skills in circuit assembly and fault-finding.
Practical Activities
- Practical 1: Logic Gate Implementation — Learners build and test basic logic gates using ICs on a breadboard, verifying truth tables. (4h)
- Practical 2: Combinational Circuit Design — Learners design and implement a half adder and a full adder, then a multiplexer circuit. (5h)
- Practical 3: Flip-Flops and Counters — Learners assemble D and JK flip-flops, then build a 4-bit asynchronous counter. (5h)
- Practical 4: Synchronous Counter and FSM — Learners design and implement a synchronous modulo-6 counter and a simple state machine. (5h)
- Practical 5: Final Project – Digital Lock — Learners integrate a keypad, combinational logic, and flip-flops to create a simple digital combination lock. (5h)
Summatives
Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.
Practical Assignments — 30%
Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.
Daily Exercises — 20%
Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.
Final Test — 50%
On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.
Final Total
| Component | Out of | Weight |
|---|---|---|
| Practical Assignments (rubric-scored) | 100% | 30% |
| Daily Average (multiple choice) | 100% | 20% |
| Final Test (multi-answer multiple choice) | 100% | 50% |
| Final Total | — | 100% |
All marks are recorded on the AATICD LMS and visible to each learner under their account.
Certificate
How it works
- Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
- Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
- You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
- If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.
Where to find it
Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
