I usually misspell words like "believe" or "receive". For words like these two I would usually google it first to see if I got the spelling right. Is there a pattern for words like these?
The old saying goes like this:
i before e except after c or when sounded like a as in neighbor and weigh
While this rule covers a large number of words, of course, there are a ton of exceptions (neither, height, weird, etc.).
