peace be upon you iso
your early care about your last semester inshallah indicates that you are on the first step of the right road of success.
your perception that you have tough literally courses should prepare you to do extra hard working in studying.
remember: Success has a price
let the price be your will and intensive effort only for these 4 months then you will be released inshallah.
just imagine that
i'm just like you .. Gonna graduate this new semester and i'm fully afraid not to pass in a course suddenly then my graduation will be delayed 7 months
do like me ..
start fighting your negative thoughts and beat your fear down
i know some people took all the literally courses at once except the introduction and i got surprised when they passed in all mashallah
they are not better than you ..
if they did it .. You can do it
at the end,
1- have faith in allah then yourself
2- make a plan
3- find a motivation
4- commit to the plan
5- work hard
