how to avoid silly mistakes

hi
as a student you may have comitted a silly mistake in your exams but keep in mind that you are not alone in this as it is a natural among students when stress comes into play .... and a fact that these cant be removed completely but rather can be avoided ....

So how to avoid these????...

1 .  Note down your mistakes in your seperate diary and while going into exam just go threw them as it will help you twice as it will give you confidence that you just need to avoid these and just before it will make your brain prepare for them

2. the common cause of a silly mistake is that you just dont read down question paper carefully while in hurry, so make that a habit to read it carefully
and after getting the answer just be more live answering it

3. remember a question paper is made to be done in a fixed time so if a question is taking you time it will be for all all others too but dont consume your much time in that and hence dont be stressed about other questions while attemping a single one.

4. sometimes bad sleep is a reason for silly mistakes therefore sleep well at night

5. adjust your timetable in a way that you need not to study just one day before exam it will relieve your stress.

6. complete all the questions which are mainly theoritical and need not require any calculations then simpler ones and then the complicated ones it will boist your confidence reduce your stress of questions and score well.
