I had pretty bad marks in 10th grade (barely passing) and I fear my 10th score will leave a negative effect on my admission application, what can I do to compensate it? I'm willing to put my 100% the next 2 years to polish my academic profile but I need help with knowing where to start. For English proficiency should I take IELTS or TOEFL? High score in which of these is considered more? Should I take SAT too?
