I have exactly the same thing, gain a few small victories to increase my morale and gather a bit of momentum. I know people warn against this because it can result in perpetually avoiding the bigger items, but I haven't suffered from this.
When I could chose I would take care of smaller, easier exams first and then focus on big one. Some collogues of mine did the opposite, first they took car of the hard exams and then do the small ones.
I don't know if you came across this [1]: "If you make your bed every morning you will have accomplished the first task of the day. It will give you a small sense of pride and it will encourage you to do another task and another and another.
By the end of the day, that one task completed will have turned into many tasks completed. Making your bed will also reinforce the fact that little things in life matter.
If you can’t do the little things right, you will never do the big things right."
