1. Rational communication: First of all, it is suggested that Xiao Zhang and his parents communicate rationally with the school to find out the specific situation, the reasons for the school's dismissal, and whether there is room for recovery. You can provide the school with a plan and proof for Xiao Zhang to receive counseling and attend cram schools to improve his grades, so that the school can see Xiao Zhang's determination and efforts.
2. Ask the higher education department for help: If the communication with the school is unsuccessful, Xiao Zhang and his parents can ask the higher education department for help, seek help and support from their superiors, and learn about their rights and the educational resources they deserve.
3. Consider other schools or educational institutions: If the above two steps can't solve the problem, Xiao Zhang and his parents can consider looking for other schools or educational institutions, such as private schools and training institutions, to see if they can accept Xiao Zhang or provide him with more suitable educational methods.
4. Enroll in self-study or online classes: If none of the above options are feasible, I should also consider enrolling in self-study or online classes, and use modern scientific and technological means such as the Internet to acquire knowledge and learning resources. This requires Xiao Zhang to have high self-control and learning ability, as well as the support and supervision of his parents.
In either case, Xiao Zhang and his parents need to take the problem seriously, handle it rationally, seek professional advice, and finally make the best decision for Xiao Zhang's future development.
