Hard to put a number to the total hours I worked for this, but I'll give an account of my year:
So I decide around this time last year (maybe a bit later, towards late august?) that I would do A-level physics in one year to get into uni for my course.. But from that point, until some time in the middle of december, I didn't work. It was mostly due to complacency, I felt like I had absolutely ages to learn the stuff, considering it was only one A-level. I was also sorting out UCAS, so I kept on putting off the time when I'd start actually teaching myself. So it was about 3-4 months of not doing anything physics-wise.
then for about a month between the middle of december and the middle of january, I worked pretty much hard for my unit 1 exam, and got an A grade in it (90% of UMS to be precise). Average of about 6-7 hours each day I think, thats a very rough estimate.
then from the beginning February to the middle of march, I worked at a steady pace, normal level of intensity, about maybe 2-3 hours each day. It was pretty comfortable, chilled. I was learning unit 2 and unit 4 stuff. Unit 2 didn't take too long actually, mainly because a lot of it was mechanics, and I did A-level maths with mechanics modules, so that helped massively.
then from the middle of march to the each of april, I dozed off, done only a little work. Probably done less than 8 hours work in the whole of this period.
then from around the beginning of may onwards to my last physics exam in late june, I worked flat out, average of 6-7 hours each day, although obviously the nearer it got to the exams, the harder I worked, so for example between my unit 4 and unit 5 exam, I would work up to 12-14 hours for some days, but obviously I would break it up into chunks, have many breaks in between, rather than do 12-14 continuous hours. Still, it was a rather hellish experience though.
I do have to add, that I did my practical assessments right at the beginning of May. For these, I didn't think i prepared adequately, mainly because I was doing this subject independently and there didn't have the lab experience from you would if you went to class. There are past papers of these practical assessments, so I looked through those, and also in my textbooks, there was a small section on it, so I read that as well, that was all I did really. I really thought I bombed the assessment (tbh I was only aiming at getting 50% of marks, this would still give me a good enough chance at getting an A grade overall), but I actually done alright, getting an A and a B in the two units, so I ended up getting roughly 75% of the marks. IMO, the practicals are a bit of a hit and miss, particularly if you're not going to have regular lab sessions like when you're in school, which was why I wasn't so much counting on them to get my required grades, I was just hoping that I could limit how badly I'd do
so yeah, thats my personal account of doing A-level physics in one year
Were there any points you just felt like saying '**** it' and stopping?Yeah when I was cramming loads of content in, especially during the frantic period of May. There were times in the early hours of the morning, when I can't help but think that I should just give up. But they were just fleeting moments, by that stage, I was just weeks from taking the exams, so giving up altogether would've been stupid. You could avoid all this and make you're life easier, by not wasting so much time in the year doing no learning/revision.
Sometimes simply not understanding something, or not having an important concept sink into my head, also made me think of quitting. But for each time this happened, I got there in the end, by simply spending more time thinking, or looking at other sources of explanation, which you find a lot on the internet. There are many helpful people in the physics part of tsr, and also on physicsforum.com who helped explain stuff to me. I guess this partly answers your question about how I maintained my motivation, I remained motivated, by increasing my understanding each time I got stuck. Theres an immense sense of relief and progression each time I got out of a jam with something which I didn't understand. So that kept me going. Its almost self-fulfilling, you have to start off being determined, and it is that determination which keeps you going when you're trying to understand something quite difficult, and once you do 'get it', theres a morale boost, and your motivation just feeds off that.
But you might ask, how do I start off being determined and motivated in the first place?
Well for me it was pretty simple, I wanted to go to uni, and the course that I wanted to do required physics at an A*-A grade. I tried to keep that in mind every time I felt like not being bothered. Still in my case, I had months when I wasn't doing any work. The beginning few months (from august to december) was due to a mixture of complacency, other distractions, doing my UCAS, and I suppose a bit of indecision with myself on whether I was really going to go for the course I chose and about doing this A-level in one year. Then from mid-march to end of april, I also slacked off, a major reason why I just suddenly stopped, was because I got rejected from the uni I really wanted to go to, that was a let down, kinda sucked my motivation and energy away. But to be quite frank, a large part was just sheer laziness
Just to add as well, going to public libraries and seeing other people knuckle down on their studies can help get you motivated.
Holy ****, did I really write all this? a wall of text
