How to Choose an Online Course Alongside School
Choose an online enrichment course by matching its level, schedule, workload and feedback to your learning goal. Plan how you will demonstrate what you learned alongside school.
Programs
Choose between optionsLast verified: 10 Oct 2026Reviewed by:SSSean Stevens
- Choose a course that teaches a specific skill or subject you want to develop.
- Choose live learning for scheduled interaction, or self-paced learning for greater control over study times.
- Budget for assignments and preparation as well as class meetings.
- Confirm prerequisites, instructor feedback and accessibility before committing.
- Keep assessed work and revisions; a certificate alone does not prove mastery.
- Compare structured courses separately from mentored research and casual video libraries.
What Succeed checks
We review public sources, provider information and recognised education-sector guidance, then focus on what helps students make practical decisions.
How official sources are used
We use official sources where available, especially for deadlines, eligibility, costs, availability and application details.
What Last verified means
Last verified is the latest date Succeed checked the key public information used in this guide. Details can still change after that date.
Why details can change
Opportunity details can change between review cycles. Always check the official source before applying or making a final decision.
Succeed's guidance is editorially independent. Providers do not approve or control the advice in our guides. If a provider relationship affects a page, we state it clearly.
What counts as an online enrichment course?
An online enrichment course adds subject study or skills practice alongside your main school education. A structured course has a planned learning sequence and tasks; confirm whether those tasks receive assessment or feedback. Live, or synchronous, learning involves scheduled meetings, while asynchronous learning involves work completed at different times, sometimes within set deadlines. UK readers may encounter enrichment alongside secondary school or sixth form; compare actual prerequisites rather than assuming US grades match UK year groups.
Stanford Online High School offers single-course enrollment to supplement another school and estimates 8–10 hours per high school course each week. Its scheduling guidance separates most courses' 2.5 weekly live hours from 5.5–7.5 hours of independent coursework. Sofia's example schedule places Life in the Cosmos at 8 PM Italy time on Tuesdays and Thursdays, alongside local school and activities. Succeed recommends building a full weekly timetable rather than judging a course by meeting hours alone; this workload example applies to Stanford OHS, not every online program.
Mentored research centers on developing and investigating a question, with independent work between meetings; it should be compared separately from a taught subject course. For example, Polygence distinguishes its ten-session Core research program from six-week structured group courses. A casual video library can help you explore a subject, but watching content alone does not establish that you completed assignments, received feedback or demonstrated a skill.
How to choose an online course alongside school
Name the concept, skill or piece of work you want to develop, then compare courses against that goal.
Common mistake: Avoid choosing only by provider name.
Compare prerequisites and sample tasks with your current knowledge, and ask what school documentation demonstrates equivalent preparation.
Common mistake: Age eligibility does not establish academic readiness.
Convert meetings into your local time for their actual calendar dates, accounting for daylight saving changes and school commitments.
Common mistake: A fixed time difference may not apply throughout.
Add meetings, reading, practice, assignments and revision to your school timetable, leaving room for sleep and assessment-heavy weeks.
Common mistake: Class hours are only part of the commitment.
Ask who reviews work, how feedback arrives, whether revision is supported and what happens after a missed meeting.
Common mistake: Recordings may not replace required participation.
Confirm device compatibility, internet needs, captions, assistive technology, accommodations, materials charges and cancellation terms before paying.
Common mistake: Treat support arrangements as unconfirmed until agreed.
Identify assessed assignments or projects you can retain, and arrange to save your work and feedback before access ends.
Common mistake: A completion document cannot explain your contribution alone.
A live course that regularly conflicts with school attendance or sleep needs a different meeting time or learning format. Do not rely on recordings or another class section unless the provider explicitly permits them.
Live, self-paced or blended: compare the formats
| Dimensions | Live course | Self-paced course | Blended course |
|---|---|---|---|
| Study schedule | Fixed class meetings | Independent study times; confirm deadlines | Fixed meetings plus independent study |
| Time zones | Convert every required meeting | Confirm submission times and support hours | Convert meetings and submission times |
| Interaction | Real-time instructor and peer interaction | Instructor contact varies by course | Live interaction plus asynchronous communication |
| Workload | Meetings, preparation and assignments | Materials, practice and assignments | Meetings and independent tasks |
| Feedback | Confirm individual assignment review | Confirm human review versus automated checks | Confirm feedback across both formats |
| Prerequisites | Course-specific knowledge and documentation | Course-specific knowledge and documentation | Course-specific knowledge and documentation |
| Accessibility | Confirm live captions and participation adjustments | Confirm accessible materials and assessment adjustments | Confirm access across meetings and materials |
| Completed work | Retain assessed tasks and feedback | Retain submissions and assessment results | Retain projects, revisions and feedback |

Common assumptions about online enrichment courses
Reality
Live courses can require attendance at a particular meeting time. CTY says missed live classes cannot be replaced by attending another timeslot.
What to do
Confirm meeting times and absence rules before choosing.
Reality
Support depends on the course, rather than the format alone. CTY says its asynchronous students can contact and meet with their instructor.
What to do
Ask how individual work is reviewed and questions answered.
Reality
A certificate records the issuer's completion criteria, which need interpretation. CS50 requires at least 70% on each problem set and the final project for its free certificate.
What to do
Pair the credential with work you can explain independently.
Reality
Research involves developing a question and completing independent investigation between meetings. Polygence distinguishes that work from its structured group courses.
What to do
Choose research when the investigation itself matches your goal.

Questions about taking an online course alongside school
Choose live learning if scheduled discussion helps you and every required meeting fits your timetable. Choose self-paced learning if you need more control over study times, but confirm deadlines and instructor support rather than assuming complete flexibility.
Use the particular course's estimate and include both meetings and independent work. Stanford OHS estimates 8–10 hours weekly per high school course, illustrating why a single extra course can be a substantial commitment rather than a small addition.
Convert meetings and submission times for their actual calendar dates, including daylight saving changes. Stanford OHS schedules in Pacific Time, while CTY lists synchronous meetings in Eastern Time; neither should be read as your local time.
Ask whether an instructor reviews individual assignments, explains errors and supports revision. CTY describes instructor-reviewed assessments and individualized feedback; use those features as comparison criteria rather than assuming every online course offers them.
It may, depending on the provider's requirements and equivalency rules. CTY accepts documentation including report cards, transcripts, teacher evaluations and school letters, with details identifying the student and relevant course; ask how your own curriculum will be assessed.
Confirm accessible materials, captions, assistive technology compatibility and any assessment or participation adjustments you need. CTY has a formal accommodation request process and asks families to start early; an existing school support plan should not be assumed to transfer automatically.
Keep your own assignments, feedback and revisions where course rules permit, alongside any completion document. CS50's final project requires code, written documentation and a demonstration video, showing how completed work can explain learning more clearly than a credential alone.
Access depends on the provider's policy, so plan to save permitted copies during study. CTY says course material access ends after completion or enrollment expiry, and advises students to download their work and instructor feedback during the course.
