Since I was sick in the beginning of year 10 and I'm only starting year 10 now ( i know it's a bit late). I will be taking 4 subjects for my edexcel igcse which are maths higher,english,bio and human bio. I have exactly one year to prepare but haven't even cover the syllabus. Is it enough to prepare for my igcses for this 2021 of may to june?
Yes. Many students do 8-10 GCSEs in 2 years, 4 in a year should be fine although Biology and Human Biology are very similar and might not be accepted as separate GCSEs in the future - a change to an alternative GCSE might be a good idea.
