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.
