Don't answer them straight away. After you complete easy MCQ, plan off to the side, write anything and everything about that topic (within reason ofc, make sure you can use it within your answer) sometimes if you miss out on something in your answer but have it dot pointed in your plan you'll gain some marks for it and some marks better than no marks, just like how slow motion better than no motion. Then after that go back and finish the easy short answer, do some more planning, and then finally write your answer and then finally do your hard MCQ.
