702? In one day I hate to say it, it's unlikely to happen. Unless you plan to write some unsupported answers. Although you should still try your hardest to get some in. I don't think they will be done to a perfect mark but depending on your time management and motivation. You would definitely need to stay on task and set a certain time for each assignment.
Do not worry about perfection because that might just slow you down.
!! ALSO FOCUS ON ASSIGNMENTS THAT ARE WORTH A LOT OF MARKS FIRST!!
Assignments are usually certain lengths as teachers assign them to be done by certain days. So this might stress you out. Think of ways to calm this anxiety down. (Listen to calming music, drink water BUT STAY ON TASK)
Really the only advice I can give is to not get distracted ( I know it is hard but think about what might happen if you don't pass..) , focus on your work, and complete assignments early next time. By doing this not only will it relives so much stress, but you can also have so much more free time.
I believe in you that you will get work done. Let me know if you need any help with questions!!
