The journey I set out on to get to Oxford or Cambridge took two years.
Not getting along with Economics I switched to History after a term in the Lower Sixth. (Not getting on with Sedbergh School, Cumbria, I left !)
My essays, though long (always, my habit, then, as now - why say something in six words when eighteen will do?) Tell Proust to write in sentences of less than six words, in paragraphs that don't flow from one page to the next (ditto Henry Miller).
Where was I?
See how a stream of consciousness turns into a cascade?
My essays (I still have them. Sad. Very sad). Were on the whole terrible. A 'C' grade is typical, a 'D' not unknown. So what happened to get me to straight As, an Oxbridge exam and a place to study Modern History at Balliol College, Oxford?
I was bedding down. Putting things in a stack. And working my pile. Perhaps my history tutors detailed notes and bullet points fed on my poor essays? Perhaps the seeds that took root were carefully tendered?
Repeated testing (my self) and learning how to retain then regurgitate great long lists of pertinent facts helped.
Having an essay style I could visualise courtesy of my Geography Teacher helped. (Think of a flower with six or so petals. Each petal is a theme. The stamen is the essay title, the step the introduction and conclusion).
Writing essays over and over again helped. Eventually I got the idea.
Try doing this for an Assignment. You can't. Yet this process, that took 24+ months to complete can be achieved over a few weeks. Perhaps a blank sheet of paper and exam conditions would be one way of treating it, instead I've coming to think of these as an 'open book' assessment. There is a deadline, and a time limit, though you're going to get far longer than the 45 minutes per essay (or was it 23 minutes) while sitting an exam.
Personally, I have to get my head to the stage where I've done the e, d, c, and b grade stuff. When I've had a chance to sieve and grade and filter and shake ... until, perhaps, I reach the stage where if called to do so I could sit this as an exam - or at least take it as a viva.
Not a convert to online learning as an exclusive platform though.
Passion for your tutor, your fellow students ... as well as the subject, is better catered for in the flesh.
The way ahead is for 'traditional' universities to buy big time into blended learning, double their intake and have a single year group rotating in and out during a SIX term year (three on campus, three on holiday or working online.)
P.S. Did I mention teachers?
Have a very good teacher, it helps. The Royal Grammar School, Newcastle where I transferred to take A' Levels delivers.
