The much-upvoted MIT materials are really good. I have actually
looked at some of them instead of just reading about them. But
I'm betting that a "lazy type person" will not learn calculus
this way, especially if you fall into a habit of watching
rather than doing.
An alternative approach might be to google 'Calculus Caltech'
and look at their course, not (necessarily) to take it but for the free
materials available. Specifically, I call attention to
the free availability of digital version of the three-part
calculus text by Marsden and Weinstein (Springer). You would need to
work a lot of problems to make any useful progress toward
your objective of getting ready for an exam. The bonus here
is that the digital version of the Student Guide is also available
for free. So you can check methods and answers to some hard
problems that give you trouble. As one might expect from
a book used at Caltech, the theory is well presented, but the
examples and problems also include practical applications that may
provide some motivation to keep going when the going gets
rough--and it will if you are taking this seriously.
I have to say that I am not primarily a calculus teacher,
but most of the courses I have taught require calculus as
a prerequisite, and I have looked seriously at several
calculus books recently, including this one. To be clear
Marsden and Weinstein is not the only excellent calculus
book around. But it is the only one I know of this quality,
breadth, and depth that is (legally) available free along
with a free student guide. Take a look; if
you hate it you will know soon enough not to have wasted
much time (or any euros).
Finally I have to say, with all due respect for the noble
aspirations involved, that I am not a fan of Khan academy for calculus.
It may be OK for an intro to some individual topics, but
for the kind of self study you have in mind, you need
a quality printed text that has been reviewed, improved
and vetted for errors over several editions.
